Dependencies: [CC65] (https://github.com/cc65/cc65) and a way to burn the ROM's. 3) Source the IC's - the spirit of this project is to contribute as little as possible to the global IC shortage and get used chips locally or from Ebay/AliExpress/etc. 4) Burn the ROMs. I use a TL866II Plus variant for the actual ROMs. -5) Solder away -6) For the PS/2-keyboard I use the 6522's Shift Register, PB6, and a 74xx74 flip flop.

If you can solder 0805 components(poorly), you should be fine. Some optional components (the microUSB connector, the 3v3 regulator, and the RF-module) require a bit more skill. +6) For the PS/2-keyboard I use the 6522's Shift Register, PB6, and a 74xx74 flip flop.

Keyboard plugs straight into the board. 7) Enjoy! Optional:
