Полигон-2

На тот случай, если ты думаешь заменить клавиатуру на AT-шную, привожу вот эту выдержку:
I got this from Cliff Lawson's Amstrad site, sorry about the crappy formatting:
When we first produced an IBM PC compatible (the 1512 in 1986) we were  extremely anxious not to upset IBM in any way so we made sure that we didn't infringe
     any of their patents. One of the few parts of the original IBM design that is actually patented is the keyboard interface so we went out of our way to
design a new keyboard interface that is quite different both in the electronic signals used and the protocols of the signals.
     We used our own proprietary design of keyboard on all the following PCs: 1512, 1640, 1286, 1386, 2086, 2286, 2386, 33286, 3386 and 4386. From the
5xxx series  of machines onwards we did what every other PC manufacturer was
then doing - using
     IBM PS/2 compatible keyboards and mice so those machine's
keyboards are "industry
     standard"
     Therefore the answer to the two questions - "Can I use an IBM PC
keyboard on any
     of those early models" and "Can a keyboard from any of those early
models be used on
     some other PC" is a definite NO. It is NOT as simple as just
changing the plug on the
     cable!
     If you have an Amstrad PC and the keyboard breaks you will need to
get a new
     keyboard from here (Because our PCs were so popular there were a
few companies
     that made "Amstrad compatible" keyboards but I'm not sure if any
of these is still in
     existence).
