I built an 8-bit RISC CPU inside of Excel. The Processor uses a custom RISC ISA that has only 10 instructions (making this a Super-RISC computer). The machine has only a single register, but is equipped with a stack to help in executing instructions. The greater computer system features 1KB of RAM and ROM each, and a 16x16px 64-color screen.
