From the project
Handmade CPU. See README.md
Not a very scary instruction set discrete logic processor.
8 bit data 16 bit address / 64KB RAM 17 bit address (in V register) / 128KW Dual Bank Video RAM 16 instructions 8 data registers and 4 pointer registers in 2 banks 1 flags register in IO port 32 input ports and 32 output ports (You can write a constant to the first 8 ports. Only registers can be written to the remaining ports.) Assembled from 74HCxx series ICs!
