Who needs to build their very own 8-bit homebrew computer in 2026? I'd say everyone should, especially if you work in IT! The Memo-1 is my personal attempt at understanding computers from the transistor up to the UI: a complete 6502-based system built from scratch, using a French Minitel as a smart terminal, with sound, joystick ports and an extension slot for expansions. In this talk, I'll share what I learned from building the Memo-1, from wiring the CPU and designing a simple bus architecture to writing a Minitel library in 6502 assembly. Beyond the nostalgia, it's been a fantastic hands-on way to rediscover and demystify how computers really work.
