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. Sajjad Ahrabi
