Mini-ITX PC in an Atari 800

      The way any keyboard works is that it makes a short-circuit between two points. In all PS2 keyboards, there is a microcontroller that detects these short-circuits and then sends a "packet" serially to the computer based on a truth table.

      Therefore, it would be dirt easy to take appart an old PS2 keyboard, rip off the microcontroller inside and solder the proper "wires" to it so that when a button is pressed on the Atari keyboard, the microcontroller "knows" which letter has been pressed.

      The only "hic" here is if the matrix of wires composing the keyboard would differ from modern keyboards. This would be very doubtful as technology tries to be backwards compatible.

Open up a PC keyboard. Pull the chip and mount into a socket (well, mount after soldering). Trace each key to see what pins it shorts together and wire the appropriate key on the atari back to the new socket. If you plan it out before wiring, you can cut down on the amount of wire used (and therefore space used)

I disagree with the "too bad he didn't get the keyboard to work" because the keyboard was crap and would hurt your fingers after a couple hours of use. The keys felt heavy and had too much tension, which required a significant amount of pressure compared to a PC keyboard.

      Unfortunately, I wasn't lucky enough to own a disk drive for it. I had the infamous tape drive. Tape, as in cassette tape. Which was very economical, but the damn thing broke almost every month. And it took 30-45 minutes to load a big program. On the upside, since it did use audio tape for its media, it could playback recorded audio in conjunction with the program. I had a spanish teaching tape that would play audio from the cassette as you interacted with characters on-screen. Pretty cool stuff considering the hardware and software limitations of that age.
