6502 Computer
Scratch-built MOS 6502 Computer
Breadboarded CPU with ROM, RAM, VIA, and UART peripherals driving LEDs, LCDs, and serial consoles at 1 MHz.
- Custom clock + single-step circuit let me probe every address/data line for debugging.
- Python assembler flashes binaries straight into EEPROM to iterate quickly.
- Ran WozMon/BASIC monitors plus my own diagnostics firmware.
