I discovered this forum a couple of months ago, and am very impressed with the amount of information here. I am very interested in the efforts to design new ternary systems, as well as the information on the Setun machines.
One thing I noticed is that there seems to be some good detailed documentation about the original Setun, but not as much about the Setun 70 hardware (although the software model seems to be well documented). This makes sense, as the original Setun was produced in numbers, but I was wondering if there is any more documentation on the Setun 70.
I thought this paragraph from "http://www.computer-museum.ru/histussr/12-2.htm" (courtesy of Google Translate) was especially intruiging:
Is there any information on this "three-digit single-wire transmission signal" and "threshold machinery operations of three-valued logic"?
(My apologies if this has been covered before.)
