F.E.M., really. It is in the bottom slot of the rear card cage (on each
machine), and is connected to the main logic board with a ribbon cable.
I did pull one out and look at it, it has a few EPROMS on it along with a
large number of other similar sized chips (24/28 pin). I did not check
numbers on the chips however... (bad me)
I noted that it appeard that something could be mounted beneath the main
logic board (threaded standoffs and such in view) but there is no
additional card mounted in either machine.

How massive are the docs? copyable by mortal man? (or precluded by
bindings and such)

Ok, there is a check point! On both systems at power-up, that entire row
of indicators is on. No amount of punching of front panel switches would
change that.

Hmmmm... not recalling any card that suggested it to be a power fail
option, where would I look to determine if these are so equipped? There
is a connector on the rear of the units (on the power supply) which
refers to somehting about a battery...
(note that I only have the two CPU chassis and the listed cards at

Hmmm... no such indications that I recall... But again, it appeared hung
(as per comments above) Sounds like that would be a good sign of initial
life tho...

Interesting. Also, the 'Standard memories' cards I referred to in the
list are indeed 3rd party memory cards. A misconfiguration of the memory
is a very real possibility as there is no telling how many hands may have
diddled with these machines before I obtained them.

Cool. Greatly appreciated! BTW: what are you running on yours? (and can
I get a copy when I get some life into these critters? (assuming of
course that HP is not tense on the issue for a machine of this vintage)
Thanks!
