There's now also a PCB-version available.

Based on the excellent YouTube series of Ben Eater, James Bates and some ideas of myself, I created this 8-bit computer

It has 256 bytes of RAM, 100+ opcodes, 5 registers, output display and 2 input-modules (manual and serial programming)

Using almost only 74HCxxx IC's it consumes 250mA

It runs fine from 1Hz up to 220KHz running all prime-numbers upto 251 in under 2 seconds

Now also running on TinyFPGA BX from 1Hz to 16MHz:
