I just recently acquired a whole bunch of stuff out of a company's
basement, including a VAX-11/780, VAX-11/750, 4 RA81's, a TU80, a
pdp-11/44, 4 RL02's, an RP06, a TS11, and spare parts and printsets
galore. (Yes, John Foust, the little pdp-11/44 in Milwaukee led to all
that.) All the equipment was brought up a flight of carpeted stairs by a
refrigerator dolly and human power, except the RP06 and the 780 where we
used a come-along and a lifting frame I made. Heavy!
 
Anyway, the 780 needs a floppy to boot. The previous owner says he
doesn't have it, and I can't find it (although I'm not done searching
yet). Is this the sort of thing that is generically available, on the
WWW
for instance, or is it something that is built up specifically for the
mix
of options I have in the machine?
 
Incidentally, does anyone here that has a 780 (I know there are several
in
the group) run theirs? It takes 3 phase power, but there are no loads
connected phase-to-phase, only phase-to-neutral (although there is a
small
3-phase transformer in the power controller, it could probably be wired
to
only use one phase or else bypassed completely) so it can run entirely on
110 volts, at about 60-70 amps continuous draw. I was thinking of using
split-phase 220, putting 2 phases on one hot and 1 on the other, then
putting the Unibus cabinet and disk and tape drives on the hot with only
1
phase on it. I figure this would about balance the draw at 40 amps, 220
volts, which isn't too unreasonable.

Richard, you *really* should post this on comp.os.vms.

These guys are before my time, as I didn't start doing VMS until 1990.
Also, see how far back the Encompass (formerly DECUS) hobbyist program
goes. You might get free licenses.
