Subject: Classic 8 acquired!

Yesterday, with considerable sweat, I and a group of students moved an
elderly PDP-8 from the locked storage area of the psychology department
to the U of Iowa Computer Science Laboratory.  The machine is
rack-mounted, and we moved it 3 or 4 blocks over campus sidewalks on
its own wheels.

The original owner says that the machine was in working condition when
unplugged, but it's been moved a few times since then, so we'll work
slowly at getting it back up.  The peripherals (An ADC, paper tape, and
what was once, probably, a mag tape controller) have lots of field wiring
which I don't trust; we may never try to bring up more than the basic
configuration with TTY, then make a parallel port of some kind so we
can speak to a modern machine as an imitation peripheral.  Any experience
anyone has with doing that kind of thing would be very helpful!

With the machine I got lots of documentation (maintenance manuals, a fair
supply of programming manuals, a vintage DECtape programming manual, even
though the machine never had DECtape, and lots of other stuff).  We will
photocopy the manuals that look useful, archive the originals, and work
from the copies.

With the machine, I also got lots of paper tape, much of it original DEC
stuff dated around 1965-66.

What can I conclude from the nomenclature found on the machine?  Here it
is:

The chassis joining the two half-backplanes has:

	On an embossed metal plaque PDP 8 / 85

The cpu half-backplane has:

	On a paper sticker:  08-291-0100 Type PDP-8-85
	On an embossed metal sticker: 8P-103

The core half-backplane has:

	On a paper tag:  08-291-1000 Type 1848.
	On an embossed metal sticker: M8-100

The FERROXCUBE core box itself has:
	On a paper label: Serial Number 51-238-71
	On an acceptance sticker: 10/21/65 (the 1/65 part is hard to read)

The power supply odometer shows 26,879.0 hours.

>From the above, I conclude our machine was made after late October, 1965;
verbally, I've heard that it was delivered to the U of Iowa in 1966.

Subject: 11/70 Front Panel


I am looking for an old style PDP-11/70 front panel.  Does anyone
out there know where I can lay my hands on one (an 11/45 will do too).

Thanx

grrr

Anybody want to "recycle" this little paperback?  Still in pretty good
condition, considering the newsprint-quality paper!

I paid half a dollar for it a few years ago, and I would rather not
toss it in the trash.  Send me a stamped, self-addressed envelope
with a couple quarters (or even a buck!) and you can have it...
