Yes definitly existed..
Same case as a VT52.
Difference may have been
a) 12 x 80
b) Uppercase only
c) 20mA only.

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.

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.
Hi
In Linux land you can download an ISO image and burn a boot cd that
will install a system. Does
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
claimed contained BG graphics. I'll have to go through them to see if any
of them say anything about th 4081 on them.

1972 - Alto Trek
probably first networked game
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
? XNS/PUP, right?
PUP, not XNS. Closer to being the first networked game (but NOT on the Alto)

IMLAC version predates it, 76-77 at PARC

I don't have any of these, and didn't know what they were, so when I asked

Anybody know of any of these? Have some maybe?
