I can't tell you much about this but I've had countless HP boards with part
numbers of 1820-something.
I went to the trouble of getting a cross-reference for IBM part numbers when
I was working on their stuff, (their numbers were 237-xxxx) but I've never
had enough HP stuff to warrant the effort.

Subject: AMD 1820-1701
Newbie question----got a bunch of boards from HP
terminals [2640 and
2645A's]
that I thought had either 8008 or 8080A chips----boards are marked
"processor" and the socketed processor chip is brown or white ceramic
with a gold "lid"---only markings are 1820-1701 on one line and I assume
a serial # on the next [7629P, 7707P, 78126GP, etc]--also has what looks
to be the AMD logo---up to the right slanting "arrow" shape.
Some of the identical looking boards do have 8008 or 8080A
installed---What do I have here??
Thanks, Craig
