I have FTP working... If you have interesting PDP-10 stuff, you can
FTP it up to 209.174.127.164 in /pub/pdp10. I have about 1.2GB to burn.
I'm still working my way up through DEC breauocracy to get permission to post
my KA-10 docs.

New subject: PDP-11/34 Power Supply
Ok, I'm working on testing the power supply for the -11/34 I picked
up recently. We deracked the system and removed the power supply.
After looking over the box we're unsure how to get inside it. We
removed the top to reveal the heat sinks and top of the transformer
but I need to get at the breaker. How do we get to it? If I plug it
in and flip the breaker, should the 2 big fans on it kick in? Looks
like 2 5V, a 15V and a 20V supplies. We think the breaker is bad but
can't get to it. How do you open these up?
Thanks

Disregard that last message. We got it out. Now to the problem.
There is a relay inside which seems to be giving us trouble. It
needs to close to get power out but doesn't seem to be closing. If
we plug it in, flip the breaker and the close the relay by hand, we
get power. What should be closing that relay? There is a second
cord coming out which went to the power control box with a 3 pin
plug. Could this be supplying power to the relay? Also does anyone
have a schematic for this switch box?
Thanks.

Thanks! We got it figured out and the properly tested the PSU. It
was fine, of course it wouldn't have been fine if we hadn't gone to
all that trouble to test it out. :-)
Anyway, the 11/34 lives. Power is good and the system came up. I
have no idea how to program this from the front panel. Any info on
that would be nice. Next I'm going to work on getting a console
hooked up and then I'll look into the hard drive.
Thanks to everyone who helped guide me through this. I'll let you
know how it goes.
