Sure. The DIL switches are small rectangular objects about 0.4" x 0.7"
and the jumpers... (Sorry, I can rarely resist that :-))
I think this is what you want:
There are 2 layouts, Revision A and Revision C.

I saw a CDC demo of that once circa 1974, as I recall it was
called "Plato", used a nice orange plasma display, limited
animation, astronomical price. CDC had grandiose plans it would
be used in schools, like every high school in the country could
afford a $2 million CDC 6600 to support it. Kinda sad actually,
once Cray left CDC they didn't have a clue as to what to do
afterwards, the big iron Cyber 6000s went nowhere, the company
wound up running payroll services (the remnants of CDC are now
known as Ceridian, a batch payroll services company).

Time to clean out at least part of my garage, especially in light of the
new arrivals. All offerings are freebies, though it would be nice if I
could get -something- in trade. ;-)
Please bear in mind two things.
1). I cannot ship anything other than the books. The disk and tape drives
are too darn big and heavy, and would require specialized packaging in any
case.
2). Dave Jenner has first pick since he E-mailed me this morning before I
posted the list. I'll post an update if he wants any of the stuff.
With that in mind, I have the following to offer:
1). HP 7974 9-track vertical tape drive, with all mounting hardware. 1600
BPI, Pertec interface, supplied with the hardware to convert it (if
desired) to a GPIB interface. Excellent condition, powers up and loads
fine, have not actually tested it with a working system.
2). (Definitely a freebie!) 83-84 vintage System Industries SMD disk
drive. Spins up, makes lots of noise, don't know if it works. Comes with
mounting rails.
3). Cipher 880 tape drive, dual-density (1600/3200). Condition: Who knows?
Freebie.
4). Books! I've got spare copies of:
DEC's 'Microsystems Handbook' for 1985
DEC's 'Introduction to Minicomputer Networks' vintage 1974
Everex 'Step 386' owner's manual
DEC PDP11 'Programming Card' quick-reference, vintage July 1975
DEC DHV11 Technical Manual.
Any takers?

Bill gave the particulars on it, band printer like the want stuff RCSRI
has 300LPM and could slew paper fast enough to empty a box fast.
The hood gas shocks would dry out and somtimes people would get a finger
bit or their head konked good.
Bill likely remembers Pat Pattenden or Paul Howard as those guys were
the old timers with those.

Yup, they made desktop PC-compatibles for a while. I remember a
dealer in College Park, MD selling them (Software'n'Things if anyone
else out there remembers them; to the best of my knowledge they aren't
operating under that name anymore if at all).
One of the big selling points was that they were upgradable by virtue
of the passive backplane. Buy an XT-compatible now, later on you can
upgrade to an AT-compatible just by swapping the CPU card for the '286
flavor.
BTW Doug, is that your face I saw gazing up at me from this morning's
San Jose Mercury News? If not, there's some guy calling himself
Doug Salot who has some stuff in his collection that's an awful lot
like things you've mentioned on this list.

When someone says Line Printer I think of something with the type
on a chain (or a drum) and the ribbon in front of the paper, and then a
bunch of hammers behind the paper. When the right character is in
front of the right position, the printer fires the hammer for that
position and pushes the paper up against the ribbon and chain/drum.
But the real definition is in how much data you have to send to the
printer to get it printing. If you have to give it a full line to get
it going then it's a line printer. If you only have to give it a
character to make it print then it isn't.

>Unless the Z80 option includes a pod that attaches to a Z80, then you
Is this "pod" something that clamps over an installed CPU? There is a test
socket for something like this. May attach to an edge connector at the back
marked "Microprocessor Probe".
Dave Jenner has bowed out on all items in the list I posted. Sam has
claimed the DEC books. The programming card and Everex book are still
available, as are all the hardware items.
Caveat emptor!
