They look like diagnostic extender boards to me, for field service... Only
one card is marked with the HP logo?
These would allow you to run a card outside of the chassis of whatever
device they were designed to service s.t. you could probe test points while
it ran, or if you wanted to probe at the bus, you could bring the signals
out from the chassis, which might have been difficult to fit probes in.
These could have gone with practically anything... there's probably as much
or better a chance that they are for use servicing a piece of test
equipment (i.e. oscilloscope, spectrum analyzer, network analyzer, ...)
than a computer.
Best,

Anyone know what either of them are called or what system(s) they go to?
Sometime in the next month or so, I will be auctioning off a complete
(working) Data General Nova 2, along with a few other very rare (from my
searches on this list) big items.
Thanks!
