Need PC-AT "keyboard BIOS" docs

You might also want to check out the software designed to read from a
serial-interface modified CueCat bar code reader, cuecat-0.3.0.tar.gz at, IIRC. The original CueCat
interfaced with the keyboard port, but there were hacks to serially
interface it, then read the character stream.

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,
