Hi--
I'm seeing posts here about systems to be rescued, but often no replies.
The classic computer rescue squad pages have no listings later than 2005.
This is a high-bandwidth list that people interested in old systems
can't neccessarily keep up with.
Could we get a seperate list going just for rescue listings,
and have either cctech or cctalk as a subscriber? That way,
folks interested only in seeing systems listings could see them
and maybe rescue systems.
Thoughts?

Last night on the CBC TV news there was an item about a decommissioned
underground NORAD bunker in North Bay, Ont. and how the Cdn gov/DoD is trying
to figure out what to do with it. The control room is still filled with
equipment, including SAGE-style-or-era video consoles (not sure that they were
SAGE, the camera went by too quickly). There was also a camera shot of what
appeared to be some other desk-style computer console. The reporter referred
to the place as being 'filled with obsolete equipment', the rest of the
systems are presumably still there too.
.. now that would be a rescue .. one can dream, but it'll probably all end up
in the scrap bins. Perhaps somebody nearby should start making inquiries.
Does anybody with a background in SAGE know whether that bunker was part of
SAGE, or what systems would be in there? I've never been really clear on how
the SAGE / DEW line / other NORAD systems related to each other or
overlapped/interconnected in operations or equipment.

In Linux land you can download an ISO image and burn a boot cd that

anybody know if something similar is possible with VMS?

Hi,
I just read your note that you just got a NBZ80 Nanocomputer.
Where did you get it and how can I get one?
I will give you a really good hint about what you can do about
documentation.
I have two books that are based entirely upon that nanocomputer.
Here are the titles of those books. Actually it is Book 1 and Book 2.
Name: Z-80 Microprocessor Programming and Interfacing.
Authors: Elizabeth A. NIchols, Joseph C. NIchols, and Peter R. Rony
Go to www.abebooks.com
This is a used bookstore and they have thousands and thousands of new,
used and out of print books.
I know that they have some listings of these books. I had Book 2, but
just got Book 1 from them.
good luck.
If you know where I can get another nanocomputer, I would appreciate it.

The 4052 I got from Jim Willing has a large collection of tapes which he

of them say anything about th 4081 on them.

This is the one that was on ebay. It was listed as a VT50. It also came with the VT50 engineering prints and a VT50 manual.

nope.. 1972 is WAY off. Docs at http://bitsavers.org/pdf/xerox/alto/trek21.pdf
Trek was developed at the Univ of Rochester, who would not have gotten any
machines as part of the university grant til the late 70's.
1974 - MazeWar, probably second networked game

PUP, not XNS. Closer to being the first networked game (but NOT on the Alto)

Anybody know of any of these? Have some maybe?

It looks like some kind of prototype. I'll open it up tonight or
tomorrow to see what it looks like on the inside. I'll try to get some more pictures. Here's what the previous owner told me when I asked him about it. It sounds like it worked for him for 6 years.
"I worked for DEC in the late 70's early 80's as a software
engineer on the PDP10/PDP20 mainframe computers. I was given
this terminal so I could work from home. When I left DEC they did not want the terminal back. So I've had it all these years. We plan to sell our house so I am doing some major house cleaning, selling on Ebay, garage sale, etc. I would say the last time it was used was around 1984. I used it frequently for about 6 years, so 1978->1984. Has not been plugged in since 1984!"

I have received request/permission from Richard Krasnow
to post the following request -----------------------------
Hello,
I have a PDP11/10 that was working fine the last time it was turned on, back in 1984 or so.
It's been in my basement since.
Can you advise where I might look to see if there is a museum that would like to inherit the beast?
I'm in the Washington, DC area, so something nearby would save on the shipping.
Thanks,
Richard

A couple of months ago I acquired a strange looking terminal that was
said to be a VT50 Decscope. A picture of it can be found on my web
site at:
http://www.woffordwitch.com/VT50.asp
The case looks like it was cast in pieces from a rough mold of a
standard VT50. Many of the key caps are not the usual color, and look
more like the key caps on the earlier VT05. I have not opened it up
and studied the inside yet to see if it has the proper "guts" of a
VT50. The previous owner said that he worked for DEC back in the
1970s, and they gave this "VT50" to him to use at home so that he
could remotely connect to a system at work.
Are there any former DEC employees (or anyone else) here who have ever
seen or heard of anything like this?
Thanks,

Hi
We have friends in the mid west (Mason City). They also seem to cover
vast distances to get anywhere at all. From their description of the
weather, the favored modes of transport are stagecoach in the summer and
dog team in the winter. Railroads are apparently ok so long as there are
no Indian raids! (sorry about that!). I think the lake ports shut in
winter. My rule of thumb used to be if I can't lift it its not
airfreight!
Its not like the old days at DEC. If you wanted to send something
(anything) to DEC Maynard say. You put it in the car took it down to the
DEC shipping section at London Heathrow. They would find a box, pack it,
label it up and that would be that until next morning when they would
ring you to say your package had arrived at Logan and would be by the
addresses desk when he got into work. (Around midday UK time). The same
thing worked in reverse.
One day I asked the shipping manager how things did not get held up in
customs. He said "Digital is the largest employer in Massachusetts and a
major contributor to the state economy"
That reminds me of another story. One day they ran out of parking space
at the Mill. So they decided to fill in part of the mill pond to make
more space. The Maynard town council said "Heritage site no you can't"
Ken Olsen said "don't worry guys I'll call the Mayor". The Mayor said
"Heritage site no you can't" Ken said "ok Mr Mayor if you look out of
your window in about two hours you will see the first of the moving
trucks relocating every DEC site in the town elsewhere. The Mayor said
"OK if you look out of your window in one hours time you will see a
fleet of council trucks loaded with dirt coming to fill the pond in for
you!"

Last time I checked, water was 1000 kilos per cubic meter, so the base
charge seems to be centered around the density of water.

Indeed. Being in the mid-west, we don't think about ports much. I can
drive to NYC in under 14 hours. Boston is farther. I think the closest
Atlantic port, drive time, would be Baltimore at around, IIRC,
9 hours. Lake Erie ports are close (2ish hours), but would almost
certainly require a shifting of the load to another vessel at an
Atlantic port somewhere.

Hi
I managed to locate an RRD42-AA (ie real Dec for 14 Pounds UK (27
Dollars US))
I aready have a Yamaha SCSI drive in an external powered case.
I also managed to locate the correct cable. (50 Way Centronics male to
50 way D type male double density pins and clip type) This fits the SCSI
connector on the back of the external box and the other (big) end goes
into the KZQSA
So...
When the cable arrives try the Yamaha drive. If its no good.
Then remove the Yamaha drive from its box and replace with the RRD42.
This way I end up with one or maybe two working SCSI drives.
Regards
Rod

Why not just get one of the plentiful early Toshibas? I have a XM-3101
(same as the Sun SL-CD) that boots my VAX4k2 (KZQSA) VAXstation 3176
(int. SCSI), SPARCstation IPX, IRIS Indigo, etc. etc.
Is anyone in the US interested in possibly swapping some PDP gear
(lights-n-switches PDP-11, or non-E/non-A PDP-8) for some (functional/
complete/runnable) Cray hardware?
My income is limited at the moment, so shipping/driving would be
difficult, but am willing to negotiate otherwise.
Interested? Contact me off list.

I was reading an application note about a Puregas heatless dryer, and one of the
applications mentioned that some IBM computers require a dry air purge. Does
anyone know which computer(s) this is referring to?
The URL of the booklet is
http://puregas.com/industrial/pdf/Drying_Compressed_Air_Booklet.pdf
These things look like they could be useful when small CFM ratings of dry air
are required.

I have a DDC 7301 drive (same manufacturer as Guy's, but different model),
and it is definitely filled with helium. Well, it was filled with helium
30 years ago ...
The DDC maintenance manual says it requires oil-free 99.995% pure helium.
The preventive maintenance procedure indicates that the helium tank is
good for about 6 months (dropping from 2200psi to 300psi).

There's something just, I don't know, wrong about the complaint that
IRIX is a dead end on this list. Discontinued, yes, but so is DOMAIN,
TSB, OS/8, CP/M ... and yet those machines are still
collected/used/discussed here. At this point, VAX OpenVMS is at roughly
the same position as IRIX- no new hardware and no major upgrades to
VMS. IRIX will be "unofficially supported" by usergroups for quite a
while yet-just look at Nekoware. They're still very well made machines,
and IRIX has its quirks, but it is a good, stable UNIX implementation
(and Indigo Magic is a pretty good UI). I suppose the collectors will
get to them (SGI does have a reputation), but for now I'm happy that
it's predominantly hobbyists- machines are cheaper that way. I haven't
been able to afford a PDP-11, but I have several IRISes. Just think of
yourself as being at the forefront.

I used one around 1980. Graphics were constructed using a programmable
character generator, a la the Intecolor. It was similar to the 4025,
which is mono, which I do have info on at http://bitsavers.org/pdf/tektronix/402x
I've been looking for technical/service docs for the 4027 and 411x/412x series
for a while now.

Hi,
I just received a DDC (Digital Development Corporation) 6200X series
fixed head disk. It includes all of the cables, power supplies and
controller for a PDP-11. Before I hook it up to one of my 11's, does
anyone have any docs on this beast?
Here are the specs as I know them:
Series: 6200X
Speed: 3450rpm
bits per track: 72000
access time: 8.7ms
tracks: 64
unformatted capacity (MB): 0.58
Supposedly there was no scheduled preventive maintenance, however DDC
made other fixed head drives that were helium filled and they needed
periodic service.
So, my question is do I need to do anything (like purge and refill)
before I use it? Does anyone have any additional info? I did get some
manuals with it, but they're mostly focused on the controller for the
PDP-11.
TIA.

See item # 120128637318
I won an SGI Personal Iris 4D/20 (1988!) workstation. I was the only
bidder and I picked it up for $40. The cosmetic condition is
excellent.
Honestly, I expected someone to come in and snipe me at the last
possible minute, so I increased my bid twice.
The hard drive will be wipe, so I nee to get an OS package for this,
which is probably as hard as finding the hardware. In several years
of watching ebay for SGI gear, this is the first time I've seen a
Personal Iris offered up, although I admit that I haven't had a
specific search for it, so one or two may have slipped through the
cracks.
Are the SGI collectors just out enjoying the nice weather?
