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.

This will also try to burn the main ROM using Minipro. Dependencies: [CC65] (https://github.com/cc65/cc65) and a way to burn the ROM's. 

I use a TL866II Plus variant for the actual ROMs.

I use the 6522's Shift Register, PB6, and a 74xx74 flip flop. See my R1 Hardware overview at 7:46: https://youtu.be/w5cA64xof2I?t=466 This is now included on the board via a USB-A connector. 

MSBasic can be assembled together with the ROM for the cost of an uncomment and a "git clone". RF tranceiver can be used to communicate with an RPi with an RF24 module.
