Hi.
I got some more parts of that disassembled PDP-11/34A yesterday. I think
I have now all PSU parts:
- power inlet unit with mains cable, circuit breaker ... and a PCB that
looks like a small PSU.
- one big transformer
- one small transformer
- one H785 battery backup regulator module
- one H745 -15 PSU module
- two H7441 +5V PSU modules
- a PCB that is labled "BATTERY CHARGER"
- a bag full of screws
Some time ago I got the front half of the BA11-K, i.e. a card cage with
the system units, all UniBus cards, power distribution panel and front
panel.
Obviously missing:
- back of the BA11-K where the PSU bricks, transformers, ... are mounted
- fans
- bulkheads for the console serial line, the serial multiplexer, RK07,
...
- UniBus extender and terminator. [1]
I got the card cage, power distribution panel, system units and all
UniBus cards in one piece, but disassembled it to clean it. I know how
to remount that, but I have no clue how all the PSU parts fit togeter
and if there are some parts missing I didn't list above. It would be
nice if someone who knows this machine could give me some hints...
I was toled that one of the PSU bricks is broken. I found some manuals
on
http://www.mainecoon.com/classiccmp/PDP-11-34A/ but I can't read
those TIFFs. I tried with xv, gimp, tiff2ps, Netscape 4.7x, Mozilla 1.2.
I took the CDR with the TIFFs with me to work and tried to view them on
a WinXP machine (puke). The machine nearly crashed when I tried to open
the files. My SGI Indogo2 is broken so I can not try some IRIX tools.
Where else can I get some schematics of the PSU bricks in a readable
form?
[1] There is an other, smaler BA11 with a custom UniBus interface from
Linotype for some photo typesetting machinery... I have the M9312
bootstrap terminator for the "beginning" of the bus where the CPU
resides.
