>OBTW, what is a NEC 8322KX D7201C?  It was in the socket above the CPU socket.

since you asked .... it is a USART (two channel comm chip). 8322 is a date code.
the NEC part number is the 7201, Intel makes an identical chip known as the
8274 (perhaps easier to find a data sheet for, if you want to fiddle with
it).  It handles the comm. and printer ports for the rainbow.
