 		 #120047 - do you mean PC?
Responding to: ???'s previous message
Andy Neil said:
The original IBM design had an 8051 in the keyboard itself, and that talked to another 8051 on the motherboard

Do you mean PC? then:
Nonononono! I don't know for sure for the original PC, but AT contains 8042 as a keyboard controller, that's basically 8048. I doubt the PC would contain '51 and then they downgraded.

The keyboard itself contained a lot of different chips (presumably based on cost) surprisingly most of them Motorolas. However, the clones might contain anything, including '51s.
