Memo-1: A Custom 6502 Computer Built from Scratch Using a Minitel Terminal

Memo-1: A 6502 computer built from scratch, using a Minitel as its terminal

I built the Memo-1, a simple 65C02-based computer for fun and learning, featuring 32K RAM and a 6551 ACIA. The system connects to a Minitel 1b as its terminal and includes support for Atari joysticks and external ROM slots. Users can boot into WOZMON or MS-BASIC directly from the startup menu, with full build instructions and source code available on GitHub.

The Minitel driver is the src/minitel.s file (yes I know, I'm the exentric one of the family).

More from this day
