Can't say I get much of a choice when it is given to me free.... :-)
I know... Given the choice, I'd never recomend the PDP11/45 as an
introduction to PDP11s, that machine is complciated. But it's what I
started on, for much the same reason :-)
It will be a little bit of time before I get to look at it properly, but I
will start with these things and try to narrow down the problem area.
Right...
Look at the fuse. If it;s violently blown (shattered glass, or
blackened), don't just replace it and try again. There is a major problem
i nthe masin side of the PSU.
If the fuse has blown softly, replaced it and try the PSU. Of course if
the fuse is OK. then try the PSU.
The outputs are on those 15 pin AMP connectors on the angled side of the
PSU. Standard (DEC) pinout, I can look it up. You want to see if there
are any outputs at all, if one particualr output is missing/incorrect, if
the entire PSU seems dead, or what.
