First of all I haven't poked around in the PSU of my 11/44 since it worked
fine when powered up. But the design of the H7140 is a lot similar to the

Long: I think it has been 20 years since I powered up this VT100 so I did

delivered the steady 5V out when the input was at approx 50V (115V input).

I saw that there were a post on PDP-8/a systems (and parts).
I have a few 8A100 chassis. These are H9300 with a G8016 regulator board.
No CPU, no memory, no frontpanels. Just the H9300 chassis including the 10
slot backplane, the 50Hz transformer assembly and the G8016 MOS memory
regulator.
BTW.

In case someone is interested. I was unable to quickly figure out if it
already was archived on bitsavers.

I have been given a PDP-11/44 and I was running through all sorts of
diagnostics to check out the machine. It seems to work fine except for the
trap test KKABD1 which fails at 23252. It passes an earlier version of the
same trap test.
The listing (thank you Jörg) is at: ftp://u58104846-pub:open4yo
The revival process of the 11/750 continues. The power supplies is working
good and then I started testing the actual machine. But that was not a very
smooth journey to success. I have in total at least three complete CPU
board sets and just after quite a lot of board swapping it got running (I

In my efforts to understand the problem with the Cache/TB Diagnostics I

When repairing machines it is some times hard to find the data sheet for a
particular component.
Sometimes google hasn't been able to find the the data sheet for me.

a lot of the data books that he received.

That's right. There were one odd swedish mini as well.

Not really a 026 but maybe contemporary with the 029:

Hello!
I have started to work slowly with the PDP-11/05 I received a year ago. It
is the big BA11-D chassis type machine. The power supply is now fixed and
working fine. A few smaller capacitors were leaking. But also one of the
big input filtering capacitors was bad and had to be replaced.

Once they could have been used by someone. Now they can only be used as a
conversation piece hanged on the wall.
I just found these on SVT Öppet Arkiv (Open Archive).
Aside from the fact that they are fascinating time documents (cloths,
haircuts, way of speaking), these are a little bit of interest to this
community. I guess that since computers were not very commonplace at that
time, SVT really liked to emp

Oops! I didn't know that they used that kind of geograpical lookup on this

I think you could use some kind of proxy to circumvent it.

I found a really nice PDP-8/e sales brochure while browsing through our
heaps of documentation.
Plenty of nice close up photos and as last picture a system with everything.
