The graphics mode allows you to draw up to six pictures with a resolution of, I think, 40x40 pixels in two colours. You can then have a little slideshow which, at the fastest display speed, is almost like a little animation. The sound editor allows you to edit a two voice song with about two octaves. You can select between piano mode and organ mode. The only difference between the two modes is that in organ mode a tone is held until the end of the note duration, while in piano mode a tone gets released much quicker. The text mode is pretty much the same as in Stellar Track. This is basically a variation on the venetian blinds effect used in Video Chess. Only this time the start position for the character shifting gets alternated on each frame. This way you display the even lines of a character in one frame and the odd lines in the next, which gets you a more 'solid' look than in Video Chess. The CompuMate had 4 4K ROM banks and 2K of RAM. Of the RAM about 256 bytes get used for the text display etc., so you only have 1.75K for your programs, graphics or songs. > I have found very little Compumate info online. I think Andrew Davie once had scans of the CompuMate manual online. Maybe he can put them back up?
