Jim,
Actually I'm just guessing that these are emulator boards. I'm not
positive what they are.
I suspect you have some ezpro adapter cards. There was a largeish box
that was the
main system that these attached to, about the size of a large cereal box
(really large). It had a terminal attached to it, and was serially
controlled, since it
predated all the gui crap that is around today.
It can talk to a PC running a debugger (e.g., DB6802)
We have one or two stashed around here, but they are
rare. I have only
seen two
on Ebay in several years that were worth buying. I guess people kept
the parts
that were labeled related to target processors, and trashed the main box
for some reason.
Power supplies were a problem in some units.
The ML 4100 analyzer would not have a socket on it,
and would have a 60 pin
cable that goes to the 4100's front connector.
Analyzer pods would be very different looking than emulator pods.
The former were black plastic. The latter were usually a beige
texture painted metal box (hinged lid, short but very large
footprint)
The ML 4400 has to have special analog circuits on the
pods, and has
several
plug in cards, ranging up to some that are pretty competitive with the
HP 16500s
with 2m x 500mhz deep capture cards in them. The bad news is that the pods
are rare, as most ML4400's were married with Pentium or Pentium Pro run
controls that had custom logic for the analyzer, and no general purpose way
to hook up to the devices under test.
