thanks for the pointers & info re grant continuity on UNIBUS.
I picked the 11/34a up myself and carted it back home safely. System
was 2 RL01s and the BA23-like (don't know the designator for the
unibus box similar to the QBUS BA23, will look later) PDP11/34a, and
an RX02 diskette drive. No disassembly of the 11/34 box till it got
home and didn't power the DC ON led on the front panel. Removed
(documenting as one went, of course :) the cards from the UNIBUS card
frame, and left just the backplane, still no DC ON light. So a
suspect PSU, which I've got out of the box now and on the bench. will
throw the meter at it in a bit to see what volts are or aren't coming
out...
