8-bit Breadboard Computer with W65C02S Processor

This repo contains the assembly code for my 6502-project.

The assembler used for this project is the excellent ca65. After assembling it, the binary is loaded onto the EEPROM using my eeprom.py script on a Raspberry Pi 4B.

Operating System

... is probably a far stretch, since it is just the programs I wrote pieced together. My "OS" consists of these functionalities:

• Supported Hardware:
  • 4x4 Matrix Keypad
  • 4x16 Characters LCD Display
  • PS/2 Keyboard
  • SPI Connection to an Arduino
• Software
  • Keyboard and keypad printer: Prints the characters you press on to the lcd
  • (Stylishly) print formated strings to the LCD
  • Sleep
  • Send various commands to the keyboard
  • Ringbuffer

It's not much, but it's honest work.
