It actually isn't much fun to use if you're trying to make real product out of it. You need external hardware for the Program Counter and although it claims to be 1 bit, the instructions are 4 bits and only the data is one bit. Of course today you could use a FPGA for the external logic, but it would be a farce. I used 4000 series CMOS. I designed and was trying to sell a very low cost PLC.
I probably have one or two if you are interested.
I meant to say that the instructions where 4 bits -- as you say, it didn't look like much fun to use -- when did this device come out (sometime in the 1970s)? If you have one going spare i would love it for my little collection
My data book (I scanned all of them) gives the copyright of 1977. Actually, surprisingly enough, we have an almost mint second edition in our library at work!
I will scratch around at home to see if I still have and ICs.
OK, 8 years ago I did the project in FPGA. There there were two processors - with the 16 bit command bus and the 17 bits data bus, and other processor with the 1 bit bus. Then I have published about it article in Russian. In magazine "Components and Technologies"...
In 80-s I was in a team who made electronics for "Buran" lunch. And there one of computers was 1-bit... Therefore I well know that item.
You can see some photo here.
I need some time for the translation. Here are references to my articles on my site...
and this is a project
Actually, could someone send me a link to the design for that thing. Like others, I wouldn't want to duplicate it, but a clearer idea of how it works would be a big help in making something similar. Send links to SparkyWatt@yourScienceQuestions.org
The Other Tesla David Blaza5 comments I find myself going to Kickstarter and Indiegogo on a regular basis these days because they have become real innovation marketplaces. As far as I'm concerned, this is where a lot of cool ...
