Apparently people have a strange interest in homebrew computers in breadboards meaninglessly blinking leds... So I made this small video (no fancy production, sorry). It lacks the register and ALU modules, so it's not doing any useful computing, just increasing Program Counter, getting 3 bytes from memory, putting them into Intruction Register and using the first 6 bits to address the Microcode Rom:

Besides this I rebuilt the clock module to include a manual clock, so I can debug step by step the computer. It will be very helpful in future.

Thanks.
