Kenn Garroch

PRINTS OF THE REALM Finding the right printer for your computer can be as difficult as winding your way through a maze. But, there's hope on the horizon - simply consult Kenn Garroch's guide to what's what and for how much. Printers range from cheap thermal narrow-paper machines to large expensive daisy wheels. The in between ground is held by the dot matrix, Epson lookalike printers. There are also colour printers which range from the cheapest pen plotters to the ribbon and ink jet machines that produce high quality prints. The bottom end of the printer market is generally held by the thermal printers, and the pen plotters. Thermal printers need either special paper, available from many stationers, or carbon transfer ribbons such as those in the Brother range (EP22/44/HR5). The pen plotters use one of four coloured pens which move horizontally across the paper. The paper moves vertically allowing characters and graphics to be drawn on the paper. They tend to be slow and are generally limited to narrow (4.5in) paper. Dot matrix is the most common type of printer these days. A vertical line of needles presses an inked or carbon ribbon onto the paper. At the bottom of the range the capabilities are limited but usually include bit image graphics and a choice of character sets. At the top end, features such as proportional spacing, near letter quality (NLQ), buffers, and downloadable character sets are available. But you pay for the extra facilities. For the more serious users, the daisy wheel type of printer may be necessary. These use a spoked wheel with a letter on each spoke. The letters are stamped against a ribbon just like a typewriter. The main problems are inflexibility, as you are limited to the characters available on the wheel. They also tend to be slow, roughly 10-20cps, and very noisy, which irritates some people. INTERFACES A snag you may run across is the type of interface that connects the printer to your computer. The most common is the Centronics parallel connection. The other main type is the serial or RS232 interface. This is usually available either as an alternative to Centronics, or as a separate adaptor for more cash (denoted by the £ sign in the list below). When buying a printer, you will probably be spoilt for choice. The first thing is to decide what you need a printer for - letter quality, listings, graphics, colour, etc. Next, decide what you can pay, and see which printers are in your price range. Once you have a selection, think of what you may need the printer for in the future. This should narrow the choice down to one or two. At this point, you should scour the advertisements in the computer press for the company that offers the best deal for the printer you want. Now you have a printer that should last for years without any problems. In case of hitches, make sure the dealer you buy the printer from has some kind of backup and guarantee policy.

PLUG IN PARAPHERNALIA Our eight-page guide to Christmas peripherals. PICK OF THE PRINTERS MONITORS IN FOCUS DISK DRIVES ASSESSED ...AND OTHER ADD-ONS DECIPHERING THE PERIPHERALS PUZZLE Once you've had a computer for a little while,you may be wondering what else you can do with it, aside from playing games and writing the odd program. Buying one of the wealth of peripherals currently on the market can open up a whole new realm of possibilities, by presenting new programming challenges, new types of software,and providing more capabilities for your computer. The problem is, what to buy, for how much,and where from? Probably the most uninteresting peripherals are printers,which are only of real use for word processing, screen dumps,and program listings. These come in many different types, sizes, prices and capabilities,from dot matrix to daisywheel. Of much more interest these days are modems. Unfortunately,they can give you that dreaded disease known as Hackery, which includes symptoms such as high telephone bills, sleepless nights and no interest in anything else. Other add-ons include light pens and touch pads for budding computer artists. These generally come with some software, but make sure when you buy that there are some details on howto program it yourself. The same applies to joysticks and tracker balls. On some machines handling these is easy but on others, such as the Spectrum and Electron, things area little more difficult. There are so many gadgets available that it would be impossible to name them all. Out of these, perhaps the most exciting are second processors, some of which can turn your humble home micro into something approaching the power of a minicomputer. Others are just add-ons to allow a sought after CP/M system. These are much more common, being available for the BBC, Commodore 64, Amstrad CPC464, and Sinclair QL, to name but a few. One point to bear in mind when you buy something extra for your micro is what you are going to do with it when you become fed up with the applications that come with it. If you make sure that there are details on how to access and control it, you will be able to write your own routines to run it, thereby giving it a whole new lease of life. PCN's six page peripherals guide should give you some idea of what is available, how much you should expect to pay, and where you can get them from. PRINTERS Many people think they can live without printers, probably due to their high prices, but eventually you'll probably want one for your microcomputer. There are a number of types around, from the more expensive daisy wheels to the cheaper thermal or ballpoint pen printers. Not to be forgotten, too, are the ubiquitous dot matrix and the ink jet types. The former are generally judged by their Epson compatibility and features. Once the type of printer has been decided upon, there are then a number of additional features to choose from, print buffers, RS232 or Centronics, graphics capabilities, redefinable character sets, and speed being just a few. A printer with all of these the Smith Corona D200 for example - can cost up to £500. Alternatively, a ballpoint pen plotter such as a MCP-40 will cost around £150, but this only takes narrow paper and doesn't give you half the facilities.

With the rapid growth of bulletin boards and the increase in Prestel-type systems, the number of cheap modems available has doubled since last year. One of the problems that beset their introduction was BABT/BSI approval. The modems had to be sent to the BABT or BSI for testing for compatibility with BT's telephone network. By the middle of 1984, there were so many modems awaiting the green sticker that people started selling them without. Things have settled down a bit now and there are a number of good modems on the market. These can be split up into different types - direct connection, acoustic coupler, single speed, or multi speed. The standard transmission speeds are 300/300 and 120005. The first is generally used for bulletin boards, although both Prestel and Telecom Gold are available on this speed. Whatever modem you buy, make sure you get one that fits your needs as far as baud rates go, otherwise you may feel a bit left out. COMMODORE COMMUNICATIONS Those with a Commodore 64 needn't feel left out. The Commodore Communications modem gives you access to Compunet, of course, and also Prestel. In the near future, Commodore is going to produce some software to allow user to user communication. If you want to use the various bulletin boards, you will have to acquire an RS232 port and a standard 300 modem. PRICE: £99.95 BATA?: Yes BAUD RATES: Full duplex 1200/75 INTERFACE: Commodore cartridge port and direct connection to BT CONTACT: Commodore dealers PRISM VTX 5000 One of the most popular modems for the Spectrum is the Prism VTX 5000. If you only want access to Micronet and Prestel it is ideal, although it can have a few problems with Interface 1. The way around this is to connect the whole system up without the modem and let it warm up (go and make a cup of coffee). Once warm, the VTX5000 can be connected (after powering down again) and it will work. PRICE: £99.95 BATA?: Yes BAUD RATES: Full duplex 1200/75 INTERFACE: Spectrum system bus and direct connection to BT CONTACT: Micronet 800, [redacted] PACE NIGHTINGALE The Pace Nightingale is another multi speed modem with both Bell and CCITT frequencies. It is a hard wire modem ie it connects directly into the telephone socket. Built mainly to be used with the BBC, for which the Commstar ROM is available, the complete package costs about £136. It is also available for any other RS232 compatible communications package. PRICE: £136.85 BATA?: Yes BAUD RATES: Full duplex 300/300 1200/75 INTERFACE: RS423/232 CONTACT: Pace Software [redacted] MINOR MIRACLES WS2000 The Minor Miracle WS2000 is great for bulletin board hackers and Prestel users alike. It lacks auto dial and auto answer facilities, which are a little expensive at £30 each but at least you're given the option. PRICE: £149.44 Auto dial and answer boards extra at £30 each BATA?: Yes BAUD RATES: Full duplex 300, 1200/75, half duplex 600,1200 INTERFACE: RS232 with DTR, RTS, CTS, DCD handshaking EXTRAS: Also has the Bell 103/113, 108, 202 and CCITT, V21, V23 tones standards fitted. CONTACT: Minor Miracles [redacted] SENDATA 700B For the ultimate in portability, it is hard to beat the Sendata 700B acoustic modem, distributed by Tandy. This modem will fit onto any standard telephone via its flexible connector so you can use it in a phone box if you don't mind the pips corrupting your data. PRICE: £235 BATA?: Yes BAUD RATES: Full duplex 300/300 INTERFACE: RS232 to the computer, and acoustic modem to BT CONTACT: Sendata [redacted] MONITORS The major excuse for not buying a monitor is that it's not strictly necessary if you have a TV. The counter arguments are that with a monitor you can see your superb high-resolution graphics with less eyestrain. The clincher is that someone else might want to watch TV. You mostly measure a monitor's quality by its bandwidth. This defines how fast the individual dots are scanned on the screen so obviously the faster it does this, the better the picture will be. 10MHz is at the low end of the range with the better colour monitors having over 20MHz. Another consideration is whether to buy colour or monochrome. The latter comes in various different coloured phosphors, usually green on green. Other options are orange on orange or grey on grey, if you want full colour, you must pay quite a lot more for high quality. If you are not too bothered about that there are a number of converted TV tube monitors available for much less. CHEAP COLOUR At the very cheap end come the JVC and Fidelity converted TV tube-type monitors. The JVCs come in two different versions, medium- and high-resolution. The 1302-2 is the high-resolution version but has a rather dirty white. This is generally caused by the quality of the phosphors used. However, it's not at all bad for £229.95. The lower priced version, the 1302-1, costs less at £149.95 but the bandwidth is not as good. MONITOR: JVC 1302-1/1302-2 PRICE: £253 RESOLUTION: 370 x 470 pixels/580 x 470 CRT SIZE: 14in/14in BANDWIDTH: 6MHz/10MHz CHARACTERS: 80 x 25/80 x 25 CONNECTION: RGB analogue/TTL SYNC: Pos or neg AVAILABILITY: Opus Supplies, [redacted] The Fidelity CM14 resembles the JVCs ie it's a converted TV tube. Its advantage is that it can be interfaced to a number of different machines, and has a built-in speaker and amplifier to allow access to, for instance, the Commodore 64's sound output. Cables for a number of machines are available from Tape Recorder Spares. One drawback to the CM14 is that it gives a better picture with some computers such as the Oric, but a bad one with others, notably the Dragon. MONITOR: Fidelity CM14 PRICE: £228 RESOLUTION: 370 x 470 pixels CRT SIZE: 14in BANDWIDTH: 12MHz CHARACTERS: 80 x 25 CONNECTION: RGB TTL, Audio input (1Kohm imp) SYNC: Pos or neg AVAILABILITY: Micro Peripherals [redacted] BETTER QUALITY Near the top of the range of colour monitors are Kaga, Microvitec, and one from Prism. The latter looks suspiciously like the Fidelity although it is better quality. The Kaga monitors come in a range, at the top of which is the Vision III. This has a black anti-glare tube and good colours. MONITOR: Kaga Vision III PRICE: £370 RESOLUTION: 640 x 440 CRT SIZE: 12in BANDWIDTH: 18MHz CHARACTERS: 80 x 25 CONNECTION: RGB AVAILABILITY: MBS Data Efficiency, [redacted] The Cub is popular and usually found attached to BBCs. The range is wide but the standard version is probably the most common. MONITOR: Microvitec Cub 1431 PRICE: £225 RESOLUTION: 452 x 585 CRT SIZE: 12in BANDWIDTH: 18MHz CHARACTERS: 80 x 25 CONNECTION: RGB TTL AVAILABILITY: Dealers MONOCHROME There are several monochromes around, and again, you pay for quality. A very average green-on-green monitor is Zenith's. This produces a fairly good picture on its 12in tube. It does have a switched option to allow the screen size to be altered between 40 or 80 columns. MONITOR: Zenith 123E PRICE: £90.85 RESOLUTION: 640 x 300 CRT SIZE: 12in BANDWIDTH: 18MHz CHARACTERS: 80 x 25 or 40 x 25 CONNECTION: Composite video AVAILABILITY: Most dealers Since most home micros now have an RF output socket as standard, many people want to use them with TVs. The quality of picture varies but the Sony Trinitron range is generally the best. MONITOR: Sony Trinitron KV1430 PRICE: £249 RESOLUTION: 320 x 250 CRT SIZE: 14in CHARACTERS: 60 x 25 CONNECTION: UHF switchable. AVAILABILITY: Electrical stores STORAGE Most home micros can only store data and programs on cassette, which can be a major hassle. The first big upgrade step that most micro owners take is some kind of fast access, mass storage system. For most machines this means a disk drive although for the Spectrum, Microdrives or Wafa drives are usually cheaper. As well as the disk/wafer drive, most machines need an interface to allow them to control the system. The odd one out is the Commodore 64 which has all the necessary bits and pieces built in. The problem here is that it can only be used with Commodore disk units (a typical Commodore gambit). SPECTRUM The main Spectrum storage system is the Sinclair Microdrive. This needs the Interface 1 to be fitted but once in, up to eight drives can be used, each giving access to 85K or so of storage. Unfortunately, this is not too reliable and is still rather slow, and there's no fancy filing system. The additional commands are those printed on the top row of the keyboard in red, so there are no random access files and no way of telling what type the file is until you try to load it. A better system is the Rotronics Wafa drive. This gives access to more storage space and a few more details about file types and sizes. The wafers, so far, have also been found to be much more reliable than the Sinclair Micro cartridges. SYSTEM: ZX Microdrive expansion pack PRICE: £99.95 COMMENTS: Comes with Interface 1, a single Microdrive, four pieces of software, an introductory cartridge, and a blank. Extra drives at £49.95 each. Interface 1 has a pseudo RS232 and a network port. AVAILABILITY: High street stores SYSTEM: Rotronics Wafa drive PRICE: £129.95 COMMENTS: Includes two drives, a word processor and a blank cartridge. Also includes an RS232 and a Centronics port. AVAILABILITY: High street stores BBC The BBC has one of the better filing systems found on home micros. From Basic you get proper random access files, loading and saving of programs and data with the big bonus that it is fast. The drawbacks are that you must have your Beeb altered and a disk controller fitted, costing around £100. You are also limited to a maximum of 31 files per disk and only four drives.The Acorn system is the most common, so if you don't buy its disk drives (which are not the best) you won't get a format program or a disk manual. Most dealers have sussed this and will sell you some other drives with the format disk included, or just the format disk at a nominal cost. The manual or a facsimile can be obtained in most good computer stores. There are a number of alternative filing systems for the BBC. These include the AMCOM, Watford, plus many others. They are not standard and some AcornSoft programs may not run on them. They do, however, improve on the Acorn DFS by getting around the 31 file limit. Which one you get depends on its price, performance, and what you want to do. Also for the BBC are a number of fast tape systems, including the Ikon Ultradrive and the Phloopy. The Ultradrive is better and costs about a quarter the price of a disk system. SYSTEM: Acorn DFS Upgrade PRICE: £115 Fitted DISK DRIVES: Cumana 100K £171.35, 200K £222 AVAILABILITY: Acorn Dealers SYSTEM: Watford DFS PRICE: In kit form £142.60 for single density, £97.75 for double density COMMENTS: The single density (100K 40 track) is more expensive due to the 8271 disk controller costing £90 AVAILABILITY: Watford Electronics [redacted] SYSTEM: Ikon Ultradrive PRICE: £79.95 COMMENTS: Pack of 6 cassettes £20.13 AVAILABILITY: Ikon Computer Products [redacted] AMSTRAD The Amstrad has a disk system in the offing, from Amstrad itself. This is a Hitachi drive and can be accessed from Basic using the definable I command to give IA, IB to select which drive, ITAPE, IDISC, ICPM, IDIR, IERA, and IUSER. From Basic there are, unfortunately, no random access files. The facilities are minimal with no proper filing. However, it does come with a full CP/M system and DR Logo fitted. The CP/M is the same good old standard that has been around for a number of years, the assembler is for the 8080 but on the whole, it paves the way for the Amstrad to become a full business system. SYSTEM: DDI-1 PRICE: £199.95 COMMENTS: Includes interface CP/M and DR Logo AVAILABILITY: High street stores INPUTS Input devices are things like joysticks, add-on keyboards, touchpads and light pens. Most of these can be simply plugged in and either come with their own software or can be used with existing games. Most computers have a minimum of a keyboard for input but some, most notably the original Spectrum Minus, have a keyboard that is less than suitable for a great deal of typing, as in word processing. Due to this, there has been a ready supply of add-on keyboards offerings from, for instance, Fuller, Cheetah, Transform and lately Sinclair itself, with the launch of the Spectrum Plus. Touchpads also seem to be booming with the release of the Touchmaster system for the Spectrum, Commodore 64, and Dragon. Also in the running is the KoalaPad but this is mainly for the Commodore 64 and the Apple. Also in the range of peripherals to help you with your graphics are light pens. These are usually for the Commodore 64 and imported from the US. A number of add-on Spectrum keyboards are available and most require fitting by the user. All you do is invalidate your guarantee by opening up the Spectrum's case, and pull out the keyboard connectors. These are then replugged into the add-on keyboard with the Spectrum circuit board and the add-on box re-assembled. A simpler way uses a buffer that plugs directly into the back of the Spectrum, so you don't have to invalidate your guarantee. KEYBOARD: Transform PRICE: £69.95 FITTING: Invalidates guarantee AVAILABILITY: Transform [redacted] KEYBOARD: Fuller FDS PRICE: £49.95 FITTING: Invalidates guarantee AVAILABILITY: Fuller [redacted] KEYBOARD: Stonechip PRICE: £59.95 FITTING: Plugs straight in AVAILABILITY: Stonechip Electronics [redacted] The peripheral for games players who want more speed and style is a joystick. The shape, size, and quality vary greatly but a rule of thumb is that quality costs more. Joysticks also fall into two types, is switched and analogue. The former is by far the most common with the usual connection being the standard Atari D plug with nine pins. Commodore, Atari, and Spectrum use this type and it is normally possible to obtain an interface for most other machines. The BBC micro is left out when it comes to joysticks as it uses the analogue type. These tend to be more expensive but more flexible to use. The major thing to watch out for is whether the stick might break just as you escape from the whirling hurling alien that is breathing down your back. One of the best is the Quickshot MkII, which comes with suction cups on the base to stop it slipping at tight moments. It also has its fire button built into the handle - good value for £12.95. Another good 'un is the Kempston Pro which doesn't have the fire button in the handle. It has two in tandem on the base allowing use by fight or left handers. It is also very solid. The BBC requires analogue sticks that plug into the analogue port at the back. The recommended version is marketed by Acorn but it seems to have been designed the wrong way round and is difficult to control. Other versions such as the Shado sticks from Spectrum at £16.95, come with an automatic centering mechanism that improves things no end. Of the light pen systems available, most and by far the best, are for the Commodore 64. The Flexidraw package from Inkwell Systems costs £140 but the accompanying software is flexible with full rubber banding, circles, fills, and a zoom. For the BBC, the best graphics package available is the BitStick. The trouble is that this does require the 6502 second processor and disk drives plus a souped-up joystick. However, for your money you get a system that will allow very high quality graphics to be designed and stored. The cleverest part is where you can zoom into part of a picture and then into a smaller part and so on until you run out of disk space. This means pictures can be designed with much more detail than is possible to see on screen. The major drawbacks are the price (£375 plus £199 for the second processor), and the lack of a suitable printer/plotter to obtain hard copy. The Spectrum is way behind in the graphics stakes with Touchmaster, DK'Tronics, and Stack being the few to produce something. The packages that come with these systems are primitive compared with other machines. The problem appears to be lack of interest from the US. The Touchmaster system costs £149.95 and is available from Touchmaster on [redacted]. The DK'Tronics light pen costs £19.95 and is available from DK'Tronics [redacted].

PRINTS CHARMING This Smith Corona printer could be a welcome and flexible friend, says Kenn Garroch. It interfaces with different types of micros, including an IBM. Printers are becoming more sophisticated at lower prices, and since most business machines are IBM compatibles, it is good idea if the printer can cope with IBM character sets and control codes, as well as the standard Epson type. The Smith Corona D200 can do all of these things plus a few more. It has a 0.8 or 2K selectable input buffer, downloadable character set capability, near letter quality (NLQ) font, normal or proportional spacing, IBM or standard (Epson) control codes and character sets, a speed of 160 characters per second in normal mode, a 9x9 dot matrix, twin Centronics and RS232 interfaces, and standard Epson bit image graphics. SETTING UP On removing the printer from the packing it immediately struck me that you need a lot of energy to heave it around. Weighing in at 8.5 kilograms it is solid and well-built. With the printer comes a manual, a power lead, and a paper rack to stop your fan folds tangling. The power plug is unusually placed on the side of the machine with the on/off switch, which proves awkward if you frequently turn the machine on and off. IN USE The most difficult task to perform before getting any printout is to set up the dip switches at the back. There are three banks of these, 20 in all, each of which, and especially the serial/parallel switches, should be set to the desired position. The manual is quite helpful here as it gives a picture of the switches with their individual functions named, plus detailed tables explaining these switches. Setting up the printer with a 0.8K buffer and ordinary character set and commands showed the impressive speed of the machine. After running this I tried the 2K buffer. This was great, especially when listing short programs, as everything goes out to the buffer and gives back command of the computer before you can say Bingo. There are a number of fonts available: NLQ, Italic, Elite and Pica. When the printer is in NLQ mode, the speed drops to around what you would expect from an Epson MX. If you want to improve the quality it's possible to mix and match print modes, such as overstrike and emphasised, but this can slow things down to the rates you would expect from daisy wheel printers. The results can be seen in the example listings. When proportional spacing is implemented with emphasised mode, the results were quite acceptable. An unusual feature of the D200 is it's hex mode. This prints the hex code numbers of the characters instead of the characters themselves. It appears to be purely a test mode since it is accessed by turning the printer on while pressing both the form and line feed buttons. One of the more difficult aspects of the machine is the facility for downloading your own character set to it. This is a very flexible way of defining your own symbols in place of some of those already there, or redefining the whole character set to give a different font. Unfortunately, this is a complex procedure involving quite a few escape codes and numbers. The characters are defined on an 11X8 matrix with descender control, starting position and stopping position. Since the print head is a 9X9 matrix, the descender control specifies whether the top eight bits or bottom eight bits are to be used; ie it moves the character up and down one bit. To redefine one character means sending 17 characters to the printer, so redefining the whole set means quite a lot more. The characters are stored in what would normally be the 2K print buffer leaving 0.8K left for the buffer itself. Another major facility of the printer is its dual interfaces, Centronics (8 or 7 bit), or serial. It isn't possible to switch between the interface via software, which is a shame, but the serial port (RS232) is flexible giving the baud rates 110, 300, 600, 1200, 2400, 4800, and 9600. Even the highest speed (9600) was reliable, and using the 2K buffer meant short print runs were over quickly as far as the computer was concerned. One aspect of the RS232 connection is that the TX and RX, and RTS, CTS pins are not reversed which means the connection is fairly simple, with no need to resort to Suss boxes and Smart cables. VERDICT The Smith Corona D200 printer is a good piece of kit, especially if you have a number of computers you wish to use it with. The provision of both Centronics and RS232 interfaces plus NLQ and a large internal print buffer make the machine a very good buy if you need something flexible, fast, and of good quality.

Speed, compatibility and quality make the D200 a good buy.

WHIRLING DAISYWHEEL Low cost letter-quality printing combined with ease-of-use appealed to Mike Batham. PRODUCT: Smith Corona L1000 Daisywheel printer PRICE: £368 inc VAT MANUFACTURER: Smith Corona OUTLETS: Smith Corona dealers Smith Corona has recently released a new range of printers aimed at the US microcomputer market. The Smith Corona L1000 is a daisywheel printer designed to be the flagship of the range (the others are all dot-matrix printers). The L1000 replaces Smith Corona's previous rock-bottom priced daisywheel, the TPl. The most obvious improvement on its predecessor is the inclusion of both parallel and serial interfaces. SETTING UP The printer comes in the usual large cardboard box enveloped in large quantities of styrofoam. The unpacking (and repacking) instructions are excellent, unlike other printers I have used that have no unpacking instructions at all. This time I didn't find myself desperately hunting for the transit screws when the carriage started making straining noises. The Smith Corona L1000 is built of moulded plastic and contains several internal foam pads intended to reduce vibration and noise. Unfortunately this still doesn't stop it from sounding like a rapidly firing machine gun without a muffler. Friction feed is standard on this printer and it will take paper up to a width of 13in. A tractor feed attachment is available as an optional extra. On the front panel are three switches. The first adjusts the pitch which can be 10, 12 or 15 characters per inch. The second is used when printing on fan-fold paper for setting the 'top of form', enabling the printer to ship the requisite number of lines depending on the paper length. The third is a form feed and also activates the self-test when pressed on power up. With its parallel and serial interfaces the L1000 can be connected to virtually any micro. And with the correct connecting leads (which must be purchased separately) the printer is very easy to set up. The manual is straightforward and well written with many explanatory diagrams. Compared to the unintelligible, complex manuals that come with many Japanese printers this is a very welcome relief. IN USE The L1000 is fairly slow, as you would expect of a daisywheel printer. The maximum speed is 12 cps in bi-directional mode. Underlining is possible, but there are no facilities for super or subscripts or for graphics. The single sheet feed set-up was almost identical to that of a typewriter (what else do you expect from Smith Corona?) and was simple to use and reliable. Not a single sheet was chewed up. The print quality was also equivalent to any typewriter. The printer ribbons are held in squarish cassettes which simply pop out at the touch of a button. The new one simply snaps into place - nothing could be simpler. Carbon ribbons are recommended in the manual, but the cloth ribbon I was provided with was more than adequate. The idiot-proofing on this printer even extends to changing the daisywheels. There is only one way they can be put on, so mistakes are eliminated. They are a bit stiff initially, but you can practice with the box each daisywheel comes in until you get the knack. Smith Corona carries a wide range of typefaces but, as with all daisywheels, if you want to use italics or anything else within a body of standard text, you have to stop and change the wheel. It's the price you pay for letter quality. The DIP switches, concealed behind a louvre on the back of the printer, allow you to choose the baud rate from a wide range when using the serial interface. Paper length and ASCII or ANSII can also be selected. I have only a few minor complaints about the L1000. For one thing, the self-test doesn't want to stop - you actually have to turn off the power. It also doesn't use the entire character set available on the wheel. The other problem is the vibrations caused when the printer is in action. If I didn't have a concrete floor I suspect the glasses would have rattled in the cupboard. . VERDICT The L1000 is a user friendly piece of hardware that even the most technology-resistant people will come to terms with. I certainly enjoyed using it, mainly because I could simply plug it in and get on with the job. The price is competitive, though the extra cost of the tractor feed may offset any price advantage compared to, say, the Juki 6100. However, most other low-cost daisywheel printers are of inferior quality.

Above are three sample printouts using (from top to bottom) Corporate 10 (characters per inch), Temp 12 and Presidential 12 daisywheels of Smith Corona's own make.
