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.
