This is my attempt to make a single board 8085 computer from a handful of 1980 era chips which were gifted to me some time ago.
My goals are:
- serial console
- i/o ports
- compact flash storage
- cp/m
Assembling is done with Alan Baldwin's suite of assemblers. Read more.
Programming is done with minipro.
- 8080/8085 Assembly Language Programming
- Assembly Language Conventions
- CP/M Memory Map
- Assembler
- Programmer
