I have been looking into this also. Here is a good link on AT Keyboards

I had this idea for a keyboard adapter for classic machines, but I
don't understand the 40-pin "keyboard BIOS" microcontroller well
enough to know if it's possible...
So... is there a good place (on the web) to learn about the
"keyboard BIOS" chip? Alternatively, is there already a project
like this that I can clone? If anyone has any examples of how
to attach a PeeCee keyboard to a 68000 or 6502 directly, without
going through a UART, I guess I'd be interested in that, too; but
since I was already planning on sticking a Z8530 or 6551 or 16550
chip on the OMNIBUS board anyway, I might as well use the same
serial port for all embedded console I/O.
Thanks for any pointers,
-ethan
