What I've been working on for the last week: A prototype for doing bringups of bus-based #FujiNet. Has RP2350 dev board to the bus edge connector at the bottom. ESP32-S3 dev board with microSD at the top. The two dev boards will communicate over USB using the new RS232/Fujiversal protocol. Lots of debug breakouts with LOTS of labels. Solder jumpers for modding. Edge uses ISA pinout; CoCo, MSX, etc. via trivial passive pin-swap adapters.

#TRS80CoCo adapter board routed. It's really ugly routing but everything is connected so good enough. #FujiNet #RetroComputing #VintageComputing #KiCad #Electronics

Why use such small vias?

For stuff of that era, I expect 10 mil hole, 10 mil anulus, 10 mil trace, and 10 mil space...
