Looking at the rack, since a Straight-8 has huge backplanes that fill
the top of the rack, there are no upper doors - I'm wondering if
that's an -8/S cabinet.

I agree, racks like that are surely rare enough to warrant a rescue!

That box is OLD. I tried to find anything that looks like it and
we start looking in the 1966 or earlier realm. I suspect it was
a much earlier box (pre super mini as PDP11 was first gen
super mini) and none of the PDP11 or PDP8 (E,I,F,M,A,L or
pdp12) used that cabinet that I know of and some of the
fossils in the DEC lab areas were sometimes odd. It's a no
match until I looks at old pdp(pre '65) pictures.
FYI all the old 8 racks I'd ever seen were mostly black and
maybe gray. Blue is an old DEC color for old systems.
This one is unusual.

I have seen Staight-8s in that style rack - they fit.
Very nice - I wish I was closer. I need to make a New York to
Knoxville run soon, but that is too far out of the way.

Hmm you are right, It can't be a PDP-8

I then thought It might be a PDP-5, but that is probably not so:

Perhaps it is for a peripheral for one of the above?

True, it is the proportions of the upper half to the lower half that
don't match. Also the lower part of the Straight-8 does not have doors
and the upper doors are attached to the computer, if the computer is
gone, I would expect that the doors would be gone too.

Look at all that airspace in this machine. Certainly a Straight-8
could fit in the Dallas mystery rack.
Realize that DEC in 1960s was fond of never standardizing their
components (especially paint jobs and cosmetics). Minor variations in
the racks really do not matter.

It looks a bit like the main cabinet for our PDP-7. The typeface of the top logo matches,
as do the apparent dimensions. I'm not saying it might not have been for an early -8,
but the Straight 8s I've seen weren't in anything like this. The side-by-side
blue doors are typical -7.
Will, thanks for rescuing this! Regardless of how it's ultimately identified,
it's clearly Old Stuffe. -- Ian
