Information

8do (also known as EightDo) is a dream CPU and 8-bit computer. It’s been a project I’ve worked on and iterated over and over again.

In it’s current state, the CPU is still being developed. It is inspired by the 6502, but with a lot more flexibility.

The Design

The CPU is 8-bit, with a 18-bit address bus. It has 4 general purpose registers and one offset / general purpose register. The stack is 1kb.
