Damn, that circular screen reminds me of the computer on the old Star Trek episode &quot;Assignment: Earth&quot;.<p>This is where the Enterprise goes back in time to a 1960&#x27;s Apollo launch. They then encounter a man from the distant future, &quot;Gary Seven&quot;, who also traveled back in time.<p>Gary Seven had a computer that looked like DEC 340 (<a href="https:&#x2F;&#x2F;www.pinterest.com&#x2F;will5967&#x2F;sci-fi-star-trek-tos-s02e2655-assignment-earth&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.pinterest.com&#x2F;will5967&#x2F;sci-fi-star-trek-tos-s02e...</a>).<p>This episode also has a very young Teri Garr as his secretary and a cat that turns into a woman with cat ears.

For those unfamiliar with the organization at work here, the Living Computer Museum is a gem of a museum located just south of Downtown Seattle. It’s chock full of amazing historical computers that you can actually use for the most part.<p>I’ve been to the museum probably a half dozen times since I discovered it two or three years ago. Each time I come back there’s something new on display. Highly recommended.

It&#x27;s a different beast, but I would love to know how the CDC-6600 dual screen console was controlled. I have no idea whether it had internal memory to keep a character-based display list or whether all tracing was controlled from the host computer. Does anyone have anything on it?

I misread the title and initially thought that it would be about the DEC VT340, a graphics terminal that I used a lot back in the 80s. Interesting that product numbers were reused.

Quite likely Germanium transistors can be replaced with their relatively inexpensive Soviet NOS copies. Many types were manufactured well into 1990s.

This is a great museum, I&#x27;ve been a bunch. They really have an amazing collection.<p>Last I went I actually talked with Keith and some other of their people who are restoring all kinds of stuff. They&#x27;re very interesting people to talk to. I highly recommend visiting and asking around if you&#x27;re in downtown Seattle some time with a free afternoon.

Is there a reason a Silicon transistor&#x2F;diode wouldn&#x27;t work here? I&#x27;m assuming it either has something to do with voltage sensitivity or frequency, but older computers like this tended to use fairly high (TTL) logic for signaling.
