A while back some one mentioned an interesting machine used for video
editing.
The local scrap dealer has one of these, the CPU card has a 8080 chip on
it and the memory card is very full. I 'd guess the box is 12" X 18.
Just introducing myself (although quite a few of you have probably
encountered me elsewhere) - Mike Ross, Scottish, living in New York just
now. Been collecting for over ten years, interested primarily in DEC and IBM
equipment from mid-60s to mid-70s. Fairly extensive DEC collection - many
8s, 11s, a couple of 15s, a couple of 10s, and a 12.
IBM so far is a few 3/360/370 front panels, although I've recently obtained
an 1800. Always willing to trade, current wants list includes:
Any IBM System/3 or System/360 or System/370
Bits for my 15s - RF15, RS09, RP02, TC15
My 12 is and always has been a bit of a mess - would love another 12, or at
least a replacement perspex for the front panel.
Also got a strange hankering for a VT05 (got a VT8e and love the shape!)
I've also got a bit of a weakness for sexy supercomputers, Have a Convex and
a couple of Connection Machines, always interested in more, maybe a Cray EL
for completeness...
A fair bit of my collection is online at:
http://www.corestore.org
Warning: corestore.org may be a bit of a mess for the next couple of weeks -
major changes to content, look & feel are under way.
Cheers!
Mike

Finally was able to get a look at the PDP 7. I think it qualifies as the find
of the week, or year, for me.
I have corresponded with those most interested in it. If interested please
contact me offlist at whoagiii(a)aol.com.

Here is the report;
I saw the PDP 7. It is a delight. It is too bad the entire Lab could not be
saved as a museum. The computer was installed in 1965 to run a 5 MEV Van de
Graff Generator which had been installed in 1964. There is still one
experiment running in the lab so it is not being shut down yet.
The PDP 7 was replaced in 1992 with a RIDGE 32. The RIDGE 32 was replaced in
1999 with a SUN IPX which runs the Van de Graf via a GPIB connection.
However the PDP7 was not removed or even disconnected. Harlan fired it up,
tried to load a program off a disk drive, by first running a punch tape.
Finally got the tape loaded and you could see action in the homemade disk
drive controller, but nada.
He was able to key in a simple program via the front switches that ran.
Classic blinkin lights, wow!
Evidently it is a Germanium transistor computer. Germanium, not being as
stable as silicon, needs more love, care and attention to keep it running.
There are two cabinets of boards and parts including extra core. It
originally came with 4K of Core but they upgraded it with 4K more for a total
of 8K.
It has a 555 DECTAPE drive, a paper tape reader and desk in the central
cabinet. It is 6 cabinets wide, however these are a narrow double door
cabinet so the entire computer doesn't seem massive. It is cute! The paper
tape punch is in the cabinet to the far left with 4K of core underneath.
Second to the left is the other 4K and the power supplies for the memory. The
third from the left is the console, desk and paper tape reader. IIRC there
are three more cabinets to the left, the last two sparsely populated. All the
cards are singles, early flip chip style.
It originally came with a KSR 33 Teletype which is long gone. They used an
ADM terminal in a roll around rack. Above the terminal is a HP1300 display.
At the top are two DEC floppy drives with the Lab's own homemade disk
controller. All this should be visible in the pictures.
There is an entire file cabinet drawer of docs and paper tapes. Several boxes
of boards and components, as Harlan said, a complete set of spares. he also
indicated they were familiar with board level repairs and that is what it
took to keep it running. They inherited lots of tapes from a PDP10 at one
time, because they could use the same ones. There are several cabinets of
small tapes.
It is a classic museum piece.
In case anybody doesn't follow any of the 6 NGs this was posted to....
As usual, I don't know this guy from Adam, please respond to him not
me.

hello,
i own a pdp11/20 and in the near future i will not have enaugh room for it
:-(
so i will find sombody who want it
the place where it is: austria, vienna, 1190
oh yes - it does not work :-(
but you can repair it as i did 10 years ago
so if you have interest and live near vienna write an email

Is there anyone who is interested in the 'ancient' INTERAK home-build computer?
I have a lot of stuff in the attic - including manuals. It seems a shame to just throw it all away!.
BTW I live near Reading in Berkshire, England - and the stuff is hardly miniature.
Cheers

I'm really not looking to steal from the drop off (that does seem a bit
wrong). My dumpster reference was to their garbage dumpster in the back.
They don't have a drop off dumpster there... just the back parking lot
near the back door. People appear to just drop stuff on the ground.
I figure I will look in the garbage dumpster to see if they toss the
unwanted CPUs in there. That is my question regarding legality... taking
>from a garbage dumpster. I know regular household garbage, as soon as you
put it on curbside for pickup, is public domain, and anyone can help
themselves to it (that includes non-bulk pickup, regular garbage... so it
is legal for someone to root thru your garbage to pull out unwanted
pre-approved credit card applications... it is just illegal for them to
submit them to get a card in your name).
So I didn't know if a business garbage dumpster was public domain as
well, since you can't drag that to a curb. (I suppose there would be a
trespassing issue, but that might be tough to enforce on a place that
allows you to come on their property to drop off stuff)

Do you mean Vectrex? The cartridge based vector video game made by CGE. Then
sold to Milton Bradley?
Try usenet: rec.games.vectrex. It is a very active newsgroup. Both for
players and programmers.
There are (RS-232 based) RAM carts avaiable. That makes testing much faster.

Shucky darn. Here I was, sitting on the other side of the continent,
reading all the writing about how k00l it would be for someone to ship
them a Model 33 or whatever, and thinking that delivery of cold drinks
would be a much more interesting, and probably more appreciated, hack.
