I've just started the rebuild of one of my PDP-8/Ms. This is an early
machine with the power supply mounted on the left of the chassis.
One potential problem I am slightly concerned about is that the front
two power transistors have been desoldered and removed. Does anyone know
if these are a vital part of the PSU and if so what the part numbers are
so I can try to source replacements?
You can see a picture here http://www.pdp8.co.uk/ (enlarged view here

If anyone else has a PSU of this type, could they take the opportunity
to take a few pictures for me. Would be really useful to have another
reference source for the rebuild.
All the best,
Toby

I'm over in San Francisco on a mixture of business and pleasure, and was
wondering if there are any electronic surplus stores I should check out?
They don't have to be chock-full of vintage computing bargains (if such
places exist anywhere any more) -- even places with surplus components would
be good...
Cheers,

This is almost exactly what I was seeing. I was able to resolve the problem
by NOT transferring the source files with FTP's binary image mode turned on.
I was then able to compile the source and I'm now in a maze of twisty
passages all alike.
Title says it. Does anyone know if the documentation for the YASBEC
single-board computer has been scanned or is otherwise available?
I have one, along with an unassembled memory board and the PCB for what
appears to be a video card. Cannot find a shred of information on either
of these.

I tried that and atext.txt looks better, but the fortran source files are
still messed up some how - at least they won't compile and the error
messages imply that there is still a record problem. I also tried a
precompiled executable with the improved atext.txt, but that doesn't work
either.
In the first part of "Three Days of the Condor", there is a PDP-11
clearly visible with tan colored panels and switches. I didn't see a
shot close enough to read the model number, however. There is also a
very loud printing terminal shown, one I haven't seen before, but its
cabinet styling is similar to the styling on the VT05 cabinet.

Subject: Re: LA30 - anyone got one?
I have an LA30 in my collection, although it isn't easily accessible
at the moment. Unfortunately, the LA30 uses a non-standard paper width,
or perhaps it was standard at the time and just isn't anymore. This
combined with immovable tractor feeds make getting paper for it difficult.

Any idea what the actual width is? I'm about to throw out a few boxes
of pinfeed paper of various sizes; maybe some is useful after all.
