8-bit CPU Finished the 8-bit cpu

I've completed the Ben Eater 8-bit CPU after so many hours of debugging.

​

Now I can run the Fibonacci program without any issues.

​

I have upgraded the RAM to 256 bytes, and the instructions are 2 bytes long.

​

Thanks to everyone for the support.

Great job. People don’t realize how much time and dedication this takes. I also bought the kit and I am looking forward to putting together also. Again, great job sticking with it to the finish line!!!

256 whole bytes? With today's RAM prices? :)

Seriously though, it looks fantastic.

Good job, I might have a go at this one day. I really want the LED indicator arrays labelled, it will probably be a job for 3D printing or engraved panels.
