Jeff Russ is a long time DEC collector in southern Indiana.
I visted him years ago. He's another one of those people with
a huge collection of software that will get around to reading
it when he gets his 30+ year old computers working again, like
the guy in Minneapolis with the stash of early 60's CDC stuff
that wants to build a museum some day that insists on reading
his 7-track 1604 tapes ON a 1604.
Jeff did put some PDP-8 stuff up at
http://bitsavers.org/bits/DEC/pdp8/papertapeImages/russ.ucs.indiana.edu/
This should also give you a hint where he is...

Its a brand of Vinyl.
I'm the one that posted maybe ten years ago about using Tygon Vinyl
to repair the gooey rollers of TU-58 drives. I can say for a fact
that those drives so repaired still work fine. The only problem
I've found over time is flat spotting if the tape is left in place.
Even if it did harden in say five years.. a foot of that is enough
to fix a few dozen drives easily and it's widely available in both
thick and thin wall types.

Don't know what fast-rewind has to say or where they got their data.
The datacenter itself (the CDC computer shown, 3150 or 6600; can't
recall now) and some of the supporting scenes were shot at the
California State University, Long Beach computing center. I was there
at the time (already graduated but hung out there as I had friends there
and used the 11/70 not shown). There may well have been other scenes
shot in Washington as Rich indicates.

One the old iron front there are machine like IMP48 I haven't find docs
for and History on Cincinati Millichron 2000 and 2100 series (1973ish).
>From the software front, I'm the odd egg, I have stuff I haven't

defunct company that used S100 hardware something like 200 disks.
As to archiving, thats a next process. It will take years and
employment as it does require money to do it. In the meantime I
copy media to other machines and occasionally read/refresh it.

Hi Rich,
I have a small (2 page) datasheet for an SMC KR2376-xx keyboard
encoder which is probably a compatible device (to check, VCC is on
pin 1, Ground is on pin 17, and the keyboard matrix connects to
21-31 (inputs) and 32-39 (outputs).
As noted above, it's only 2 pages. It gives you the pinout, typical
connection diagram, character matrix assignment chart and some
waveform charts.
If this is of use to you, I can scan it for ya.
Regards,
Dave

Does anyone have a PDF copy of the data sheet for the General

The best way is to keep tape image files, or just plain binaries, on a
PC (or whatever) and load them in over a serial line. Have a look at
the Kevin McQuiggin's PDP-8 page at Highgate:
http://highgate.comm.sfu.ca/pdp8/
Kevin keeps a mirror of David Gesswein's site which has lots of
diagnostics and documentation, but there are more diagnostic tapes on
Aaron Nabil's site at www.pdp8.org

BTW, thinking of that RL8A, I have the prints for it... Al, are those

I wish you'd said something a few days ago. Thom send SIX large Gaylord
boxs of cables to the shredder yesterday! :-(

Cables are MUCH more difficult to find than the boards themselves!
esp things like the cable that goes from a TD8/E to a TU56

No idea as to the DC, but the story on the streets around Cambridge
Massachusetts is that most of the "junk" used to make the film props
came from Eli Heffron's & Sons on Hampshire Street in Cambridge. At the
time, they sold "stuff" by the pound in piles. As "stuff" aged it got
moved to cheaper piles.
Eli's was good stuff until lately. You can still get just about any
minicomputer/test-gear part you want, but not at bargain prices.
I'll never forget the day I saw a beautiful redhead girl walk in to
Eli's, immediately notice a PDP-8 board and get all excited about the
bargain find (and she correctly identified it). She had been looking for
one for *her* PDP-8. I was in love.
My favorite Eli score was a TDC Microfiche camera, with lens and film
reels for $50.00. Since I worked for TDC I recognized it and parted out
the camera to my customers for about $2000.00.
