R200 Relay Computer

Even after almost half year break on the project I still cannot find motivation to continue. After playing with the R200 emulator I got a little disappointed with the fact that you cannot really make any meaningful program with just 64 words of ROM. I wasn't even able to figure out 24-bit square root. Still open for suggestions on some kind of cool program ideas.

Thanks to  Alexander Tsidaev there's now awesome GUI for the emulator. Check out the gif of the emulator running fibonacci.R200 program at x10 speed.

I had idea of this machine since 2009, so you can imagine how slowly the process is going. But it mostly due to fact that my interest for the project spikes for several weeks and then fades for the rest of the year. It actually took me just two months of weekends in order to design and assemble that hookup on the pic from scratch.

But I am in no hurry. It’s not like the machine can become even more out of date.
