PJ5 - 03 - Clock PCB (V1)

Our Clock PCB for the PJ5 TTL CPU project. Variable clock speed from 4Mhz down to 0.0018hz (8.9 minutes). Also generates the second phase of the main clock, has run/pause/halt functionality and additionally gives us LED brightness controls.. Coupe of minor mistakes, so there will be another revision of this PCB. More details on our blog - https://pj5cpu.wordpress.com/
