I've been trying to puzzle out a board in front of
me, loaded with
Intel chips. The CPU on it is a 16MHz 80186 - it appears to be an
interface peripheral board for some Astro-Med product. Externally, it
has a serial port and a GPIB port. What's strange to me is that I
can't identify the parts that appear to be the GPIB buffers - a pair
of 28-pin Intel D8293s. There's also a P82C08, which I can't find any
hard info on.
So... does anyone recognize the Intel part numbers P82C08 or D8293
(yes, I know the P is plastic and the D is ceramic; it's the parts
themselves I'm curious about).
Hmm...The 8208 is a DRAM controller. Dunno about the 8293.
