Welcome back to the 6309 Unleashed DIY retro computer series! In this episode, we: - Wire up clean power, reset, and clock signals - Add buffers so the 6309 doesn’t fight every chip on the bus - Show how a reset supervisor IC keeps things sane - Use an Arduino Mega as a test bench to simulate signals, stress-test ideas, and set the stage for the PLDs in upcoming episodes This isn’t just “blink an LED” — it’s real 80s-style computer engineering with modern twists, corny humor, and lots of lessons along the way. If you’re into retro computing, 6809/6309 CPUs, homebrew systems, this series is for you.

Episode 1: Breadboard to NitrOS-9 — The Roadmap to a 6309 DIY Computer

 🚀 Episode 1 is Here!

The wait is over: Episode 1 of 6309 Unleashed has just dropped!

In this episode, I lay out the roadmap for building a fully featured retro computer around the Hitachi 6309 CPU. From the early hurdles (power, reset, clocks, and buffers) to the big milestones (NitrOS-9 Level 1 and Level 2), this is where the adventure really begins.

Expect a mix of technical deep dives, a dash of retro humor, and the occasional detour into “what was I thinking?” territory. If you’re into blinking LEDs, bus buffers, or just want to see how far one can push an 8-bit CPU with 16-bit muscles, this is for you.

Episode 0 has also been remastered and reuploaded — so if you missed the intro, or just want the cleaner cut, you can catch up there too.
