Flight Deck Joystick

Sinclair User

HARDWARE WORLD With ever-increasing amounts of peripherals available for Sinclair computers, users are finding it more and more difficult to know what to buy. We present a buyer's guide to joysticks, keyboard and printers and review the best of the rest from the 1984 add-on market. Joysticks are a popular addition to the Spectrum and many people find it essential for zapping aliens or flying a simulator. In the last year there have been a number of interfaces and joysticks launched, some with more success than others. Nearly all joysticks have accepted a common standard, that of Atari which was the first company to add joysticks to a computer. The style of the joysticks may vary but the connection to the interface remains the same. To use a joystick some form of interface is needed. One, or more, of three standards are normally used. 'Cursor', sometimes known as 'Protek', simulates the four cursor keys for the directions with 0 as fire, 'Sinclair' allows for up to two joysticks and simulates keys 1 to 5 and 6 to 0 respectively and 'Kempston' which does not simulate any of the keys but uses a port address. The most common of those is the Kempston but it is by no means universal. To overcome that a programmable interface can be used which allows you to use any key for any direction or fire. The method of programming varies, some need a tape to be LOADed, while others require you to press a key and then to move the joystick in the direction which that key will simulate; some have physical connections which must be made to signify the key and others simply use a stored memory of which keys are to be used. GRANT DESIGNS & EEC Two designs combine the interface and joystick in one. The Grant Designs Spectrum Stick and a similar one from EEC clip to the Spectrum keyboard over the cursor keys and use a mechanical system to press the keys. Inside the Spectrum Stick there are two frames which move independently up and down, and left and right; to those are attached ramps which push little feet onto the relevant keys. The EEC joystick is more substantial. The casing is a one-piece moulding which fits snugly onto the Spectrum case. Inside that the stick is securely joined to a shaped plate which presses on one or more levers which in turn depress the key. Both are priced at £9.95 and are far cheaper than anything else on the market. Provided they are used with restraint they are better than nothing. RAM TURBO INTERFACE The RAM Turbo interface from Fleet Electronics is what the Sinclair Interface 2 should have been and was not. As well as having two joystick ports, it has a ROM cartridge slot. Moreover, one of the joystick ports can be used for Kempston compatible games and the other can be used as a Protek compatible port. It is similar in size to the Interface 2 but the rear connector is full Spectrum-size as opposed to the Interface 2 ZX-81 size. The area surrounding the joystick port is large enough to take a standard joystick connector. Users who have either built their own joystick or use the Flight Link joystick will have found problems with Interface 2 as the left-hand, most commonly used, port is too near the raised ROM slot. In order to prevent users fitting the interface with the power on (the surest way to blow up your Spectrum) it incorporates a 'Spectrum Protect Adapter', a loop of plastic which covers the power socket on the Spectrum so that the lead must be removed before fitting. If you are considering the Interface 2 then think again; the RAM Turbo interface is better designed and better value for money, costing £22.95. PROTEK INTERFACE The new switchable interface from Protek can be configured for all three of the standards by using a switch on the back. The interface is dead-ended, so it must be the last add-on fitted. As with the Turbo interface, it is liable to crash if used with a twin fire button joystick. Its main drawback is that in the Protek position the top row of keys is disabled, while in the Sinclair position only the 6,7,8,9 and 0 keys are disabled, which could make some games difficult to play. The switch would have to be moved, the key pressed, and the switch returned to its original position. Despite the above problems, which should not affect most users, the interface is easy to use and covers most games on the market. It is priced at £19.95. ELR INTERFACE The programmable interface from East London Robotics for the Spectrum has the distinction of being the cheapest on the market at only £10.00, if bought together with a Trickstick. The interface, as ELR would be the first to admit, was designed to be 'cheap and cheerful' and it is, even to the extent of being uncased. In order to program it small metal clips are used to connect pins which represent the various rows and columns of the keys on the keyboard. That is fiddly and time consuming if you need to reprogram it, but has the advantage that once programmed it is usable from power up. If the interface is purchased separately its price is £15.00. COMCON INTERFACE Frel Ltd market the ComCon programmable interface. Any key on the keyboard can be programmed and there is provision for two fire buttons. To match the interface Frel also markets two compatible joysticks. The interface is of simple design and to program it you have to plug the relevant lead into the pin you want. That can be done with a program running and the keyboard is not disabled. Any joystick with a standard plug can be used and if that has only one fire button then the F1 lead is used. To allow for other add-ons there is an extender card which rises vertically from the front of the board. The two joysticks which Frel markets are the Flightlink and the Quickshot II which has been adapted to have the independent fire buttons, F1 on the trigger and F2 on top. At £19.95 the interface is one of the least expensive and the ease of programming should ensure steady sales. The two joysticks are £10.50 for the Flightlink and £13.95 for the Quickshot, both less £2.00 if ordered with the interface. CCI INTERFACE The interface from Custom Cable International needs a software tape to program it. It can accept any standard joystick; there is no extender card, so it must be the last add-on plugged in. Programming the interface is straightforward. In all, only 10 keypresses are needed plus two to confirm everything is order. The program is written entirely in BASIC which makes it very easy to customise. This is a good interface and competitively priced at £15.00, but it could have been even better if the instructions had been more detailed. PAGE & RAINBOW The Page and Rainbow interfaces are of the kind where you must push a key, move the joystick, release the joystick again for the four positions plus fire, again for the diagonals, again for the diagonals plus fire and finally the fire button on its own. All of that can be done with the game running as the keyboard can still be used. Some people will find that time consuming and fiddly. The one really useful feature of the Page interface is a rapid fire switch. When that is in the up position it simulates the fire button being held down, very handy for the 'zap everything in sight' type of game. The Rainbow interface includes a beep amplifier. With the Rainbow interface at £24.00 and the Page one at £26.00, they deserve consideration provided you do not mind the time and hassle of programming them. FOX ELECTRONICS The programmable interface from Fox Electronics, on the other hand, is probably the easiest of all to program. You only have to flick a switch once you have told it which keys to use. When the switch is up a menu is displayed on the screen. You have the option of creating a new key set, from any of the forty keys or selecting, with a single keystroke, one of the sixteen sets already created. Pressing the E key exits to Basic to load the game and programs the joystick. If necessary the key sets can be saved on tape. Leaving the switch down enables the Spectrum to ignore interface. Inside the interface is a RAM chip and a small ni-cad battery, and on power down it retains the information in its memory for a minimum of six months. When switched on the interface pages the Spectrum ROM and jumps to the program held in its RAM. The program then transfers itself into the Spectrum RAM, pages the ROM back in and puts the menu on the screen. On pressing the E key the program transfers itself back into its own RAM, sets up the joystick and clears the Spectrum memory. Any new key sets created are therefore saved in the process. All that sounds clever but it also has two beneficial side-effects. When the switch is down, the interface causes a hardware reset; in other words, if you have a game running you can jump out of it without pulling the plug - a saving on plug wear. Secondly, details are available from Fox for a machine code programmer to adapt the interface as a pseudo ROM. Often used routines such as toolkits, printer driver programs or complete character sets could then be loaded at the flick of a switch. At £28.95 the interface is excellent value. TRICKSTICK One of the more unusual joystick devices launched in 1984 was the long awaited Trickstick from East London Robotics. In fact, to describe it as a joystick is misleading. It is a 7in long black cylinder with six touch sensitive pads which simulate the four joystick movements, plus two fire buttons. The Trickstick comes with an interface, up to eight of which can be plugged in at any one time, and has the option to give proportional movement on specially written games. It simulates the Kempston joystick so there are many games available on which it can be used. The touch pads use your body as an aerial to pick up mains hum. That is converted by the electronics to simulate the key press. As some people are better aerials than others the sensitivity of the stick can be altered by a small screw near the top. A minor fault is that the lead from the interface to the stick fouls the power lead. It takes some getting used to unlike a joystick, but once mastered is just as useful. As it has no moving parts it should stand up to wear and tear and it is quicker than most others. It costs £34.50. Nineteen eighty-four has been a quiet year for standard joysticks with only two given much publicity. DELTA 3S The Delta 38 from Voltmace has two independent fire buttons, one of which is doubled up for left or right handed players, and rotary switches are used on it. Those switches give it a light action and it can be comfortably held in the hand. At £10.00 the joystick is good value, its solid construction should ensure long life. SUPER CHAMP The Super Champ, currently marketed by Dean Electronics, is unusual in that the cable is held in the base. For use the cable is pulled out and, when you have finished, rotating the stick winds the cable inside. The stick is very long and thin and has two fire buttons, one on top and one in the trigger position; those both operate the same switch. The base is, as expected, larger than usual and has four rubber suckers underneath. Because the stick rotates there has to be a certain amount of play in the pivot. That makes precise control difficult unless you hold down the centre. Despite that the joystick works tolerably and the convenience of not having the wire lying around almost makes up for it. The Super Champ is priced at £12.95. RAT Finally, if the advertising is to be believed, the age of conventional joysticks is past and the future belongs to the RAT and its offspring. The RAT (Remote Action Transmitter) operates in a similar fashion to TV remote control handsets; you simply wave it in the general direction of the screen and press the touch-sensitive movement and fire buttons. It is sold with a receiving unit that connects to the Spectrum and is compatible with most popular Spectrum software. The RAT is powered by a normal PP3 battery which fits into the underbelly of the handset. The first of its kind, the RAT suffers minor teething problems and can cause excessive handache but, like the Trickstick, you will soon grow fond of it. The price is £29.95 from Cheetah Marketing and high street stores. Grant Designs, Bank House, Reepham, Norwich, Norfolk NR10 4JJ. Tel: (0603) 870852. EEC, [redacted].

Crash

BATTLEFIELD JOYSTICK Joysticks are your most immediate connection with any game you play - the man-machine interface. The melting joystick makes a nice image for an advertiser who's suggesting that his games can beat anything, but do joysticks in real life really stand up to the beating they receive, are they tough enough for the job, do they move well, are the handles right, will the buttons fire? The CRASH reviewing team settled down for a weekend of joystick bashing on several types and makes, and here we look at the results... There are now many makes of joystick available, and almost as many types as there are makes. Each boasts design innovations so that it is better than all the others - and they come in a range of prices too. We all know that joysticks on arcade machines take a battering, so too do those at home. Do they stand up? We tested 19 joysticks from well known manufacturers to see how they all compared. A joystick must be able to withstand games that require fast and repeated movement, so what better than Ocean's Daley Thompson's Decathlon? We used the Commodore version of the game because it is more violent than the Spectrum! But it isn't only toughness; joysticks must also be capable of fine and positive movement, comfortable to use with sensible fire buttons. Several arcade skill games were used to test four major points for both the stick action and the fire button action. TRAVEL means the maximum movement between opposite poles (e.g. up/down) on the stick, and how far the fire button had to be depressed. On stick action over 1.5 inches was considered to be very long. Oddly, some of the short sticks had longer to travel than the taller sticks. ACTION FORCE means the amount of hand or finger pressure required to keep the stick pressed over or the fire button down. REACTION SPEED indicates how fast contact is made, how quickly the action affects the game, and how well rapid movements can be made (especially rapid fire buttons). RESPONSE/FEEDBACK indicates how positive the stick or fire action feels and whether there is any physical or audible feedback to tell the player that contact has been made. ERGONOMICS how useful is the stick for hand held playing, and how well does it operate on a table top. Is the stick well designed for comfort, ease of fire action and general stability. After preliminary testing, the joysticks all went through ten minutes of the Decathlon to see how long they were likely to stand up to use. During this test, some joysticks broke. Finally, all the sticks have 9 pin D connectors and are Atari compatible on the pin outs. They all need an interface of one sort or another to work with the Spectrum (except the clip-ons). Some offer 2 independent fire actions, but these only work with either a Cambridge interface or the programmable Comcon from Frei Ltd., which was the interface used for this test. Each joystick review is split into two halves; firstly a brief technical breakdown; secondly the review team's report. PRO ACE Supplier: Sumklock Microware, [redacted] Price: £12.95 Lever Action: Strong plastic handle suspended between two plastic bushes. Central copper star acting as self-centering spring and contacting 4 copper rivets Fire Action: Oblong fire button at 12 o'clock operating copper contact switch. Trigger button at tip of stick activates copper plate contact. Ergonomics: Average size easy grip enclosure for handheld operation. Rubber feet for table operation. Left and righthanders welcome. Lead: Plastic moulded D connector and retaining grommet. Weak point: Copper contact star can weaken and deform. Soft copper contact surface creates dust and can oxidise if not used over long period. STICK ACTION Travel: long Action force: very hard Reaction speed: slow Response/feedback: very poor and irregular - up/down was not too bad but left/right was terrible, and a lot of slack FIRE ACTION Travel: long on stick button, very long on base button. Action force: medium. Reaction speed: poor Response/feedback: poor, no indication or 'feel'; rather rubbery. Ergonomics: the shaped base fits the hand well with a well positioned left or right hand base fire button, but very unstable on a table top, especially with the sticky travel. The long thin stick is quite comfortable to hold. Life expectancy: top fire button pulls out too easily, the copper contacts bend out of shape easily with use, causing erratic response. The general stick response and travel means that the handle will take a beating on hard, fast games. SPECTRUM MECHANICAL Supplier: EEC Ltd., [redacted] Price: £9.95 Lever Action: Plastic shaft strengthened by long selftapping screw suspended in rubber mount activates via cam plate four flexible key actuating fingers. Fire Action: None Fixing: integrally moulded clip grips. Main body flexes under use. STICK ACTION Travel: long Action force: heavy. Reaction speed: poor Response/feedback: no feedback and generally poor response as casing flexes greatly during play. Ergonomics: This unit clips over the edges of the computer and is made from one piece. This means that together with the stiff stick movement the unit flexes heavily during use, especially with more violent games, and this sometimes renders the key pressed inoperable. The tendency to move away from position during play can also disenable any 8 directional movement. Life expectancy: not very high on fast games, and indeed there may be the slight chance of damaging the computer in a game like the Decathlon. FLIGHTLINK Supplier: Flightlink Control Ltd., [redacted] Price: £10.50 Lever Action: Short Steel short suspended in brass bell bush and compression spring for self-centering action. Plastic bush activates subminiature microswitches. Fire Action: 2 miniature square fire buttons at 6 o'clock. Two independent fire actions in combination with appropriate interface. Ergonomics: No rubber feet. Lever shaped body for handheld operation. Left and right-handers welcome. Lead: D type connector with plastic cover. No grommet Weak point: Lead entry point unprotected. STICK ACTION Travel: long. Action force: very light Reaction speed: fast. Response/feedback: good, positive lock at end of travel for secondary compass points, but tends to slide on primary compass points (left/right/up/down). FIRE ACTION Travel: medium long. Action force: light. Reaction speed: fast - good for rapid fire. Response/feedback: some slack but reasonably firm and positive. Ergonomics: handheld is very good because of small size and light weight but overall a bit pathetic on the table top. The 2 independent fire buttons are in a straight line, which make them a bit awkward for table use, as supporting hand is in the way. Life expectancy: because of fight action and metal construction, stands up to a hard game very well. Life should be quite good. SLIK STIK Supplier: Consumer Electronics Ltd., [redacted] Price: £9.95 Lever Action: Short rubber mounted steel shaft contacting 4 rigid contact plates in end position. Tough short throw movement. Fire Action: 1 left-hand round fire button at left 10/11 o'clock position in enclosure. No trigger button. Ergonomics: No rubber feet or suction cups. Small well rounded body for handheld operation. Left-handers only Lead: Plastic moulded D type connector and sleeved retaining grommet Weak point: Moulded plastic support wall for contact plates can crack and break off. STICK ACTION Travel: very short Action force: medium Reaction speed: good. Response/feedback: quite positive feel and solid end stop with solid clunk. FIRE ACTION Travel: short Action force: medium to hard. Reaction speed: good. Response/feedback: sort of sticky feel, but solid end stop with loud clunk. Ergonomics: lightweight construction and small size make it good for handheld use and reasonably stable on a table top, the corner position of the fire button is good for right handers, but poor for left handers. Life expectancy: Pretty good because of the short stick, short travel and steel shaft. It feels quite safe even on a hard game. KEMPSTON PRO 5000 Supplier: Kempston Micro Electronics Ltd., [redacted] Price: £13.50 Lever Action: Strong steel shall suspended in rubber bush. Leaf contact switches actuated by nylon bush. Fire Action: 2 large arcade style round fire buttons actuating leaf contact switches Ergonomics: Average size well rounded enclosure for handheld operation. Rubber feet for table top operation. Lead: Plastic moulded D type connector and moulded sleeved grommet. Week point: Body flexes under use. STICK ACTION Travel: short Action force: medium Reaction speed: instant Response/feedback: no audible feedback but fairly good response overall. FIRE ACTION Travel: very short. Action force: very light - good rapid fire. Reaction speed: fast. Response/feedback: good with hard, positive feel Ergonomics: not very good for handheld use with the large base but reasonably steady on a table top. The two large arcade style fire buttons on the base are well placed for left or right-hand use, and the round knob shaped stick is comfortable to hold. The slightly stiffer action of the stick on this version of the 5000 make it slightly more tiring to use on the Decathlon. Life expectancy: Good KEMPSTON PRO 3000 Supplier: Kempston Micro Electronics Ltd., [redacted] Price: £12.75 Lever Action: Hollow plastic shaft supported in rubber washer actuating 4 leaf contact switches. Fire Action: 2 trigger buttons (trigger finger and thumb) and one banana shaped fire button at 12'o clock. All fire buttons operate one leaf contact switch. Ergonomics: Small rubber feet. Handheld or table top operated. Lead: Moulded D type connector and moulded sleeved grommet Weak point: very weak hollow plastic shaft STICK ACTION Travel: medium long Action force: medium to hard. Reaction speed: quite fast Response/feedback: slow, very soggy feel and imprecise. FIRE ACTION Travel: base button medium - top and trigger buttons long. Action force: medium Reaction speed: poor Response/feedback: not very positive, soggy feel and no feedback. Ergonomics: similar to PRO 1000 - top fire button badly placed for handheld use. On a table the base button is in the way of second hand holding base fire button which occupies most of the front of the base. Trigger fire is quite well placed. Life expectancy: the hard game proved too much for this joystick, which broke, the stick snapping off at the base, before its ten minutes were up. The somewhat thin hollow plastic stick obviously lowers life expectancy rather drastically if hard games are going to be played with it. KEMPSTON PRO 1000 Supplier: Kempston Micro Electronics Ltd., [redacted] Price: £10.99 Lever Action: Hollow plastic shaft supported in rubber washer actuating 4 leaf contact switches. Fire Action: Banana shaped red fire button operates leaf contact switch. Ergonomics: Handheld or table top operated (rubber feet). Lead: Moulded D type connector and moulded sleeved grommet Weak point: Very weak hollow plastic shaft STICK ACTION Travel: short. Action force: hard. Reaction speed: medium. Response/feedback: no feedback, rubbery feel to the stick and even on a slow game it felt as though the handle might break at any second FIRE ACTION Travel: medium long Action force: medium hard and tiring for rapid fire. Reaction speed: slow. Response/feedback: no feedback, again - very rubbery. Ergonomics: seems fine for handheld use at first, but not well designed as centre of gravity is all wrong to be able to operate stick and fire at the same time. Not too bad on a table top, quite stable with supporting hand holding it tightly, but too much resistance for single handed stick operation. Again, the long, curving base fire button gets in the way of the supporting hand. Life expectancy: Joystick was rendered useless after two minutes of Decathlon, because the stick snapped off at the base. Same thin, hollow Construction as the Pro 3000. COMPETITION PRO Supplier: Euromax Electonice Ltd., [redacted] Price: £16.95 Lever Action: Strong steel shaft suspended in rubber bush. 4 industry standard V3 microswitches actuated by plastic bush. Fire Action: 2 large arcade style round fire buttons actuating leaf contact switches. Ergonomics: Average size well rounded enclosure for handheld operation. Rubber feet for table top operation. Plastic moulded 0 type connector and moulded sleeved grommet. Weak point: Body flexes under action STICK ACTION Travel: short, in fact just about right. Action force: light. Reaction speed: instant. Response/feedback: although in most respects identical to the Pro 5000 this stick has audible clicks - generally very good. FIRE ACTION Travel: very short. Action force: very light - good rapid fire Reaction speed: Fast. Response speed: good, with hard positive feel. Ergonomics: base too large for handheld use, stable on table top with well placed left hand fire buttons on base. Comfortable knob shaped slick. Life expectancy: Good. ATARI Supplier: Atari International, [redacted]. Price: £7.50 Lever Action: Nylon shaft supported between pivot point and upper shoulder support. Nylon actuator ring activates 4 dome switches on pcb. Plastic gaiter and deformation of ring creates self-centering force. Fire Action: One round fire button at 10/1 1 o'clock activates dome switch. Ergonomics: Average size square body for hand-held operation Rubber feet for table top operation. Lead: Moulded D typo connector and moulded sleeved grommet. Weak Point: Actuator ring will wear and snap. STICK ACTION Travel: short Action Force: light to medium. Reaction: good Response/feedback: no feedback, soggy feel which gets soggier with use and hardens up with disuse. FIRE ACTION Travel: medium. Action Force: light. Reaction Speed: good - very good rapid fire Response/Feedback: very firm feel but no feedback. Ergonomics: the hand-sized square base and light construction are ideal for hand-held use, although the corner placed fire button can be awkward, and isn't very good for left-handers. Life Expectancy: not too long, but reasonable considering price. SUPER JOY Supplier: Spectravideo Ltd., [redacted] Price: £9.95 Lever Action: Plastic shaft with actuator ring activating 4 dome switches on pcb. Deformation of ring creates self centering action. Shaft Supported between lower pivot point and upper shoulder bearing. Fire Action: 3 firing buttons, on lever thumb switch, two on side of enclosure (10 and 2 o'clock). All three activate dome switches. Ergonomics: Slim body suitable for handheld operation. 4 suction cups for table operation. Lead: Moulded D type connector and moulded sleeved grommet. Weak point: Actuator ring will wear and snap. STICK ACTION Travel: short. Action force: very light. Reaction speed: medium fast. Response/feedback: not very good - a lot of play in the stick and then over travel. FIRE ACTION Travel: short. Action force: light Reaction speed: medium to slow. Response/feedback: no good for rapid fire with top stick button and oddly placed twin fires on either side of the base. Quite a positive click. Ergonomics: quite good for handheld use with slim sides to the base - we found the side buttons hard to use. On the table the narrow base with large suction cups make single handed stick operation hopeless, and the cups tend to give it a soggy feel overall. The long stick travel was found to be too much for the Decathlon and the thin base, even with supporting hand, makes wobble too much in a fast game. Life expectancy: if the unit had actually had good suction cups, it wood have smashed to bits within minutes on the Decathlon - as it was the units base only lasted the ten minutes before coming apart at the base seam with the side buttons sliding inside. It was repairable. FAMOUS REDBALL Supplier: CGL, [redacted] Price: £23 Lever Action: Long and hefty steel shaft supported in elastomeric bearing. Plastic ball sleeve activates 4 leaf contact switches Fire Action: Thumb activated lever switch activates leaf contact via central tappet and dome head. Round fire button at 10/11 o'clock activates further leaf contact. Ergonomics: Large body with 4 rubber feet designed for table top operation Lead: Moulded D type connector and integrally moulded sleeved retaining grommet. Special feature: Button selector switch for lever or enclosure fire button control. Weak point: Lever suspension allows slight axial movement which can activate fire leaf contact by mistake. STICK ACTION Travel: medium long. Action force: medium Reaction speed: good. Response/feedback: no audible feedback, response quite springy. FIRE ACTION Travel: short to contact with over travel. Action force: light Reaction speed: last - good rapid fire from base not bad from stick top Response/feedback: positive response, feels solid on base, less so on stick button. Ergonomics: solid and heavy base make it very stable, but hard to hand hold. The round knob shaped stick is comfortable and very good for single handed use as the top fire button can be disenabled for hand over the top action. The disenabling switch is at the rear of the base. Flexing of the centre steel shaft however, can cause unwanted firing action during direction movement, and is particularly pronounced during fast games. Life expectancy: very good due to solid construction. THREE WAY DELUXE Supplier: CGL, [redacted] Price: £25 Lever Action: Long tough steel shaft suspended in elastomeric bearing support. Plastic ball sleeve activates 4 leaf contact switches Fire Action: Thumb lever switch activates leaf contact via tappet and dome head. Extra fire button at 10/11 o'clock activates further leaf contact switch. Ergonomics: Moulded D type connector end moulded sleeved retaining grommet. Special feature: Fire function selector disables body mounted fire button. Three different grips provided, which can be pushed onto steel shaft. Grips have 360 degree rotation. Weak point: Shaft suspension allows slight axial movement which can trigger off fire button inadvertently. STICK ACTION Travel: very long Action force: medium. Reaction speed: good. Response/feedback: some over travel, otherwise a positive end stop, no audible clicks. FIRE ACTION Travel: medium on stick top and long on base button. Action force: light Reaction speed: fast, good rapid fire from either button. Response/feedback: light clicks, rather soft in feel. Ergonomics: base identical to Famous Red Ball, so not good for handheld use but steady on table top. A base mounted slide switch allows either both or only one fire button to operate. The steel centre shaft has pull off handle which may be replaced with one of two others, so there is a moulded grip handle. This allows a wide range of individual grips and is an unusual feature. Again, like the Famous Red Ball, the flexing centre shaft can cause unwanted fire action during directional movement. On a fast game, the tendency of the handles to twist around the shaft can be disorienting. Life expectancy: stood up very well, and because of solid construction, should have a long life. THE BOSS Supplier: CGL, [redacted] Price: £13 Lever Action: Steel shaft supported in elastomeric bearing. Plastic ball sleeve activates 4 leaf contact switches. Fire Action: Thumb activated lever switch activates leaf contact via tappet and dome head. Ergonomics: Average size body for handheld operation. 4 rubber feet for table top operation. Lever grip can be rotated. Lead: Moulded D type connector and integrally moulded sleeved retaining grommet. Weak point: Lever suspension allows slight movement which can activate fire leaf contact by mistake. STICK ACTION Travel: long on over travel Action force: medium. Reaction speed: medium. Response/feedback: no feedback, response a little soft but reasonable. FIRE ACTION Travel: short to contact with over travel. Action force: very light. Reaction speed: fast - good rapid fire. Response/feedback: good positive response, no feedback. Ergonomics: rather heavy, solid construction and large base makes it awkward to hand hold, although a rebated underlie at the front and back do help. Moulded handle grip and top stick fire are reasonable for either hand use or table top, where the weight makes it reasonably stable. The handle twists on the base, which is uncomfortable and disorienting. Life expectancy: quite good as the whole is very solid but the long over travel on the tall stick may put it at risk on regular hard games. VOLTMACE DELTA 3S Supplier: Voltmace Ltd, [redacted] Price: £10.00 Lever Action: Short steel shaft, gimble mechanism operating two small rotary switches, two small tension springs for self-centering action. Fire Action: 3 small fire buttons operating rubber membrane switches. Two independent fire actions in conjunction with appropriate interface. Central green fire button F1, two red buttons for F2. Ergonomics: Calculator style flat enclosure for hand-held operation. No rubber feel for table top operation. Lead: Moulded D type connector, no grommet. Weak Point: Life of Rotary switch contacts may be limited, lead entry point. STICK ACTION Travel: long over-travel but short dead travel. Action Force: exceptionally light. Reaction Speed: instant. Response/Feedback: very good response, not much feedback. FIRE ACTION Travel: very short - more over travel. Action Force: very light. Reaction Speed: very good. Response/Feedback: nice firm end to travel, not much feedback. Ergonomics: above average for hand-held use with light stick travel and fire buttons within easy reach of thumb, ibis features 2 independent fire actions, with fire one using one button, and fire 2 using two for left or right-handed players. Very well laid out and light. It's long base makes it reasonable on the table although it moves in frenzied games. Life Expectancy: quite good because of the steel shaft. It 'feels' safe. SPECTRUM STICK Supplier: Grant Design Ltd., [redacted] Price: £9.95 Lever Action: Plastic handle suspended by lower pivot point and two upper slide plates with integrally moulded leaf spring for sell-centering. Slide plate cams activate key plungers. Fire Action: None Fixing: Left and right grip arms with stud and wing nuts. Weak point: Plastic arm will wear and snap. STICK ACTION Travel: very long. Action force: very light. Reaction speed: good. Response/feedback: no audible feedback, but feels positive. Ergonomics: this is a cursor key clip on joystick unit which mechanically depresses the cursor keys. It operates well in 8 directions and is quickly attached to the keyboard, leaving the zero key free for fire action. The short slick moves freely and feels good. Obviously it cannot be handheld and when attached to the computer is very stable! Life expectancy; surprisingly good, considering its light construction but not designed to withstand the onslaught of too many Decathlons. ARCADE PROFESSIONAL Supplier: Euromax Electronics Ltd., [redacted] Price: £28.95 Lever Action: Short and strong steel shaft rotating in ball point bush compressed spring and nylon washer for self-centering action. 4 industry standard V3 lever operated microswitches actuated by nylon bush. Extra plastic end stop bush for 8 or 4 way action. Fire Action: 2 large body-mounted arcade style round fire buttons. Ergonomics: Large arcade style console for two hand operation. Heavy metal base with foam pad for stable table top use. Console top out of GRP with silver flake black high-gloss paint. Lead: Plastic moulded D type connector. Non retaining round grommet. Weak point: None STICK ACTION Travel: medium to long Action force: light. Reaction speed: instant. Response/feedback: good to excellent, very positive. FIRE ACTION Travel: medium to long. Action force: light. Reaction speed: very fast - excellent for rapid fire. Response/feedback: good, solid feel and clunky feedback. Ergonomics: handheld - you've got to be joking! It's huge! the large sized arcade style box makes it excellently stable and it has a low centre of gravity, hardly moves at all. Nice big arcade style fire buttons make life easy. Life expectancy: very good, it feels solid. Everyone felt this was just about the best on a hard game. QUICKSHOT 1 Supplier: Spectravideo Ltd, [redacted] Price: £9.95 Lever Action: Plastic shaft supported between pivot point and upper shoulder support. Plastic actuator ring actuates 4 dome switches on pcb. Deformation of ring creates sell-centering effect. Fire Action: One round fire button at 10/11 o'clock activates dome switch. Lever thumb switch activates dome switch. Ergonomics: Average size well rounded body for hand-held operation. 4 suction pads for table top operation. Lead: Moulded D type connector and moulded sleeved retaining grommet. Weak Point: Very weak actuator ring will wear and snap. STICK ACTION Travel: very long. Action Force: light to medium. Reaction Speed: good. Response/Feedback: audible click, but it didn't feel very responsive. FIRE ACTION Travel: short Action Force: medium. Reaction Speed: slow. Response/Feedback: audible click with positive feel, but resistance makes for poor rapid fire speeds Ergonomics: the long stick and large base with big suckers makes it poor for hand-held use, but reasonably stable on a table with the suction cups, although they give it a soggy feel. Life expectancy: not very long, showed signs of splitting along base seam, and the base area of the stick was starting to wear where it enters the base. QUICKSHOT 2 Supplier: Spectravideo Ltd., [redacted] Price: £11.95 Lever Action: Plastic shaft supported between pivot point and upper shoulder support. Plastic actuator ring activates 4 dome switches on pcb. Defamation of ring creates self centering force. Fire Action: Large trigger fire button and lever thumb switch both activating dome switches. Ergonomics: Average size moulded body for handheld operation. 4 suction feet for table top operation. Lead: Moulded D type connector and integrally moulded sleeved retaining grommet. Special feature: Rapid fire action increases firing power on single shot games. Provided constant stream of firing signals. Will not work with all interfaces, as it requires non standard 5V supply on the D connector. Weak point: Plastic actuator ring will wear and snap. STICK ACTION Travel: medium long Action force: medium Reaction speed: good Response/feedback: no feedback, overall rather soggy feel to it. FIRE ACTION Travel: very short. Action force: light. Reaction speed: good - reasonable rapid fire. Response/feedback: good, positive feel and audible click. Ergonomics: no good for hand held use with large base and suction cups in the way, although this makes it good on a table. This joystick has a Rapid Fire slide switch, which is badly placed so that the supporting hand tends to knock it on, and it doesn't always work with the Spectrum, causing all sorts of disasters! Top stick and trigger fire buttons are usefully placed. Life expectancy: better than Quickshot 1, medium expectancy - the long stick and travel means it gets rather a battering in fast games, especially with the full hand grip required. TRIGA COMMAND Supplier: Datel Electronics, [redacted] Price: £19.99 (excl. P & P) Lever Action: Nylon shaft supported between pivot point and upper ball support. Nylon actuator ring activates 4 dome switches on pcb. Deformation of ring creates self-centering action. Fire Action: Trigger button forces large copper contact to solid contact post. Ergonomics: Average size square body for handheld operation or with 3 separate suction cups for table operation. Large handgrip with trigger button. Lead: Moulded U type connector and moulded sleeved grommet. Weak point: Actuator ring and handgrip rotation stoppers will snap. STICK ACTION Travel: very long, although travel to response is short with long over travel. Action force: very light Reaction: very fast. Response/feedback: good response, long travel after contact makes life easy, no audible feedback. FIRE ACTION Travel: short to response, long over travel. Action force: very light. Reaction speed: medium - trigger action tires finger rapidly on fast firing games. Response/feedback: audible click - long travel after contact makes for a tiring fire action. Ergonomics: too large a base for comfortable handheld use, but light action and solid base make it very steady on a table. The large girth stick is comfortable to hold but the trigger fire is awkwardly pieced so that the finger tends to squeeze oh it, and its edges are quite sharp. This stick only has a trigger fire. Life expectancy: The large handle lends to twist too much and this combined with the long over travel makes it feel unsafe on a hard game, as though the stick would break off it survived the ten minutes however. THE ARCADE Supplier: Euromax Electronics Ltd., [redacted] Price: £15.95 Lever Action: Steel shaft supported in tough rubber washer. Plastic dome on shaft activates 4 subminiature lever microswitches. Self-centering with rubber washer and plastic nose for endstop. Fire Action: Single large red fire button activates subminiature microswitch. Light action. Ergonomics: Hand or table operation with 4 rubber feet. Solid feel and operation. Lead: Moulded D type connector and moulded sleeved grommet. Weak point: None. STICK ACTION Travel: very short Action force: hard. Reaction speed: slow and not very delicate. Response/feedback: not very good because of overall stiffness. FIRE ACTION Travel: long Action force: medium Reaction speed: slow - not good for rapid fire. Response/feedback: audible click, but soggy in feel. Ergonomics: quite good to hold, although the smallish, tapered base cause the hand to slip forwards in use. On the table, very stable with quiet games, although moves a bit on the faster ones because of hard action force required. Life expectancy: quite good, seems robust enough.

Your Spectrum

LOOK MUM, NO WIRES! Standing lonely amidst a sea of joystick manufacturers all claiming their product's compatibility with any games program on the market - thanks to the immense wizardry of their technical department - here are are two joysticks who've ignored all the electrical bits and pieces. Both devices are designed to be clamped atop the Spectrum in such a way as to depress the '5', '6', '7' and '8' keys when the 'stick' is moved in a particular direction. Compatible with all games using the direction keys for movement (or those allowing you to define the keys), both joysticks are priced at £9.95 - which is a good deal cheaper then their electronic counterparts.

COMPETITIVE JOYSTICK Regular readers of Hardware World may remember the mechanical joystick reviewed in the February issue. New from EEC Ltd is another joystick which clips over the Spectrum case and presses the 5, 6, 7 and 8 cursor keys mechanically in response to the movement of the stick. The casing is a one-piece moulding which fits very snugly to the Spectrum case. Inside that the stick is joined securely to a shaped plate which then presses down on one or more levers to depress the key. The design appears to be well-thought-out, with attention paid to its strength. A previous criticism of this type of joystick was that it would work only with games configured to use the cursor keys and that is still so but EEC includes details of more than 60 games which can be played with the joystick. Retailing at £9.95, or from EEC with an extra 55 pence, postage, the joystick is competitively priced. EEC is at [redacted].

CURSE THE CURSORS So many games now use the cursor keys 5-6-7-8 for directional control that anything to make life easier is a welcome addition to the game player's equipment. In our last issue we took a look at joystick controllers, and we will be looking more closely at the joysticks themselves in a future issue. In the meantime, here are two neat attachments which will take some of the sting out of the cursor curse. The serious problem with cursor keys for playing is that they are just not ergonomic. It is quite natural for the brain to interpret direction quite physically - in other words, for up and down control to be in that configuration, and left and right similarly. This is why key positions like Q/A and N/M are sensible. Q/A and Z/X are not so good because the two sets of keys, one for each hand, are too close. Directional keys that come in a straight line are poor in comparison because in the heat of play, the brain can become confused as to which set is which. Now if, on top of that, you add the factor of the peculiar layout of Spectrum cursor keys, which is left-down - up-right, you can see that you have what might be called split hand control. A fairly new idea has been to develop joysticks which simply clip over the top of the Spectrum keyboard and mechanically depress the cursor keys. The movement is transmitted by means of levers activated by a joystick. This means the joystick can be moved left to create left movement, right for right movement, and so on, just as you would if you used a programmed joystick. The obvious advantage t o this system is its cost. There are no electronics involved, no wires, no edge connectors and no hardware programming. The obvious disadvantage is that the joystick will only control the cursor keys, and by no means all games on the market opt for them. Nevertheless, a great many games do, or have user definable keys, or make provision increasingly for cursor type joysticks. Obviously if a game does offer user-definable keys, then its no problem at all to set up for a clip-over joystick. E.E.C. Ltd. have brought out such a clip-on cursor joystick called Spectrum Mechanical Joystick. This comes as a one-piece clip-over unit which press fits over the shoulder of the Spectrum. Slightly off-centre (to take into account the position of the cursors) is the raised box containing the levers. From this rises the joystick itself. Below the box surface the joystick, which can rock in all directions, is fixed to a shaped cam which in turn activates the four levers. A disadvantage of this system is that the pressure on the key pads is uneven, so that in play it requires different pressures for different directions, and the transmission of pressure seems quite uneven when it is used for 8-directional control. Overall the construction is strong - almost too strong, which means you have to hold the unit in place when playing fast and furious games. Its main advantage is that it clips on quite quickly and without any fuss. Another contender for the clip-on cursor joystick is the Spectrum-Stick from Grant Design Ltd. This one comes in three pieces, and so packs into an amazingly small box for posting. The central unit is a closed box a mere three inches by one and three-quarters and an inch high. Two Z-shaped arms are attached to this by means of white plastic bolts. The advantage of this system is that the bolts can be well tightened onto the shoulder of the Spectrum, and when in place the unit has no tendency to slide or wobble in play. A useful touch is that the hidden cursor key symbols are all reproduced on top of the unit so that you can still use them. The joystick itself is extremely positive in action - in fact so much so that I'm sure it's the best "feel" joystick I've used, and compares on equal terms with any of the more famous names. It reproduces 8-directional movement with perfect accuracy, and is so light to handle that there is no risk of computer movement or even of joystick damage through over-ardent playing! These clip-on cursor joysticks are a worthwhile investment, I think, even if you have another type (unless of course it's already a cursor interface joystick). And both makes mentioned here, do leave the rest of the keys free for use. Of course you don't get a fire button with them, but then, quite a lot of fast games use two or even three effects keys and you can't cope with that on any joystick at the moment. So, from now on, its not only plug in and turn on but also clip on. The Spectrum Mechanical Joystick: is priced at £9.95 (incl. p+p) from E.E.C. Ltd., [redacted]. The Spectrum-Stick is priced at £9.95 (incl. p+p) from Grant Design Ltd. [redacted]. Both joysticks should be available from good computer retail outlets.
