How about the B-1700? I used one once and it was
really interesting.
Has anyone archived any old tapes or software for those machines? Any
known emulators?
The situation on that series is a little better than most of the Burroughs
machines. CHM has a not-quite last generation machine (19xx) as does William
Donzelli. Some software came with the CHM machine, I went to one of the last
guys who took care of them in TN a few years ago and brought back a large
stash of maint docs/sw and a card set from a 19xx he had in storage. Since
there are a lot of B-1xxx alums in the Bay Area, there is some possiblity
the CHM machine could be restored. A hardware simulation of the machine
would be a challenge.
Unfortunately, there were lots of interesting software/langs for the
machine, and almost nothing has survived that I've been able to find. Same
is true for the B5xxx/B6xxx etc. series. Univac and Burroughs had a scorched
earth policy and almost nothing survives today from their old machines.
