Made a cartridge for the #FujiNet #PicoROM prototype. All data is transferred over the bus, it doesn't plug into the serial port in the back of the CoCo. As a prototype it's still missing things and has to be plugged into a computer which is what the USB-C connector is sticking out of the top. #RaspberryPiPico #RetroComputing #VintageComputing #TRS80CoCo

Sorted the problem with the #LT6502 and console, not sure why but I swapped the TXE and TXF pins on the CPLD and it worked.
Now running basic with almost 48K of RAM.
Using #PicoROM to get the firmware working.
Need to add other bits now (VIA, 6521 and compact flash).

@fozztexx is working on bringing up the #FujiNet WiFi Adapter for #MSX systems. He's prototyping the interface using a #PicoROM. Looking good :)
