Additional details for each board, including a bill of materials and technical documentation, are on their respective Github pages:
A z80ctrl board or RomWBW is required to load games into memory and launch them.
Many thanks to JLCPCB for sponsoring the prototypes of these boards. Whether you want to manufacture my boards for your RC2014, or you need to prototype your own electronic project, JLCPCB is an excellent choice. They produce top quality PCBs for an incredibly low price and their service is fast. I routinely get 5 day or quicker turnaround on my projects, order placed to board in hand.
