Prototype of #TRS80 CoCo #FujiNet which uses the cartridge bus –and not the CoCo RS232 serial port– booting up the FujiNet CONFIG program. Shows the splash and goes into the menu! The prototype board uses a PicoROM wired direct to the bus, all IO is sent out over the USB port. This is the same technique currently being used by the MSX FujiNet prototype too.

@fozztexx You can tell it's a prototype because it is purple and has blue wires! If it was green and had blue wires, then it could either be a prototype or a Tandy/Radio Shack/TRS-80 commercial product.
