Greetings:
I am looking for a source reference and/or details of writing ISRs for the
IBM-AT keyboard, which is used in all 286, 386, 486 machines.  I know how
to program the IBM-PC keyboard and have written several ISRs for it.
However, I have not been able to put together all the information I need
about the AT keyboard.

I have read the AT technical reference and some of the BIOS listings, but
still feel I don't have all the details.

I would appreciate it if anyone could lay out the protocol for me or point
me to good reference source.

Thank you in advance.
