Hey all --
Got my hands on a pair of Nuclear Data ND-812's (thanks, Mike!) and I'm
looking for any info/software for them. I've got the stuff off of
Bitsavers already :). 12-bit machine from ~1971, toggle switches and
blinky lights.
Actually, these are BR2412s -- evidently military versions of the
ND-812. They're green :). The other major differences (from glancing
through the maintainance docs on Bitsavers and comparing to mine) are
that the ND-812 used core memory, and the machines I have use DRAM
(Looks like 24kw of Intel 1103's!). And as a result the BR2412 has a
completely different power supply, which I'd love to have information
for so I can test it out before powering these things on. And I assume
the color scheme was different :).
Anyone know the history of this machine (or even the company itself?
Did they make any other computers?) I can't find too much information
on the 'net...
