And my best find of all: a virtually mint, seemingly
unused HP9000/300
computer with 7958B hard drive (150 Mb IIRC) and 9144A 16-track tape drive.
A label on the 98574 CPU module indicated it's been upgraded to a 375 which
is just about the ultimate of the 300-series. A 68030 processor running at
50MHz and 16 Mb of RAM. Nice!
My new 9000/375 system was built into a 19" rack enclosure which was in
turn bolted into a fiberglas transit case about 3' tall, 2' wide by about
2.5' deep. It was part of a military surplus system. I did not get a chance
to find the AN system designation on the rack or case, just that it weighed
97 pounds and required two persons to carry.
US Army Maneuver Control System, Version 10. The box you have was box #2
of what would have bene configured as a 3-box or 6-box set.
Other boxes included one which held the monitor (and doubled as a desk),
the communications processor, and the powersupply. If you look, you should
find a tag from either Loral or Ford Aerospace, as they were the MCS version
10 contractor.
