View Full Version : New vintage computing user group and upcoming event

February 1st, 2005, 02:09 PM
Hello all,

Several collectors in the mid-atlantic region, but reaching as far north as New York, are forming a new group called MARCH -- mid-atlantic retro computing hobbyists. Our first event will be an exhibit at the upcoming Trenton Computer Festival, where the dozen or so of us will demonstrate vintage computers for all to lust over. We expect to be a big hit at the show: it's the 30th anniversary of TCF, and at our exhibit, people will get to not just see but actually use the technology of (approximately) 30 years ago! All are welcome to participate. :)

Please see our Yahoo group: http://groups.yahoo.com/group/midatlanticretro/

The TCF site is http://www.tcf-nj.org

For questions, please contact me at evan947@yahoo.com.

Here are the photos I took of the MARCH display this weekend at the Trenton Computer Fest.
I'm sorry I didn't get a shot of every display; they were all excellent.
I will add thumbnails and captions later.

Nice pics. I recognize most of the hardware, but there's one that I really like, but it has me scratching my head. Can anyone identify the machine farthest to the left in \sunday\dcp0004.jpg? (It's featured in a few other pics too).

Do you mean the Tektronix 4010 terminal (sans shroud)?

Could be, I've never seen a Tektronix like that before, but the one I'm looking at is fully-clothed. It's the one-piece, on a little stand of some sort. The only other Tektronix terminal I've ever seen looked like it came right out of George Jetson's house, kinda stylized & futuristic looking. I used to have a Tektronics keyboard that I thought was kinda kewl, it had a little trackball built-in, but I never did find a terminal to go with it.

I didn't spend much time looking at that terminal when I was there, but it seemed to be very similar to one I used in college. I believe it was some kind of Tektronix plasma display terminal; I can't remember the exact model number. Ours had a shroud to shield the screen from overhead lights, which would tend to wash out whatever was being displayed. One could do vector line drawings on it as well as text. Everything would persist on the screen until the clear code was sent (or the clear button was pressed), at which time the entire screen would flash and whatever had been there was erased, much like shaking an Etch-a-Sketch, only much faster. :)

So they were used pretty much with high-end graphics workstations?
(I just did a quick google, and you're right about them not being "normal" (raster-scan) devices. They use a different standard called "storage tube" technology). Here's a link explaining how it works, but it sounds like what you're describing.

Sounds like the same idea old-style storage scopes used.

i saw the pics

I would have loved to have attended. going to an event like that would be too cool. I would be interested in every old computer. Let us know when future events like this will be. Hopefully I will be able to attend one of these years.

Found a webpage. Mystery solved, it appears to be the same animal.

I keep a list of relevant events on the web site for my newsletter, it's at http://news.computercollector.com.

(For anyone who was wondering -- "Computer Collector" the vcforum user and my "Computer Collector Newsletter" are completely unrelated.)
