Remarks
This one started life as an ordinary low-res program in late 1982, and was later upgraded to WRX16 format. It lets you input the data points of any waveform (assumed repetitive) and computes the Fourier transform. Or give it the transform (Fourier co-efficients) and it computes the wave. You can even do two independent waveforms, plotted X vs Y (such as Lissajous figures). Sample run contains such an X-Y plot in the shape of Mickey Mouse; by taking various numbers of harmonics into account, you can see Mickey transform from an egg into a mouse... (Where else could you ever find a program so useless?)
