RDF-600 Floppy Adapter for MSX Computers.
Based on the TDC-600
This is a clone of the TDC-600 Disk Adadpter for MSX Computers redesigned for a more compact footprint. This should fit inside standard MSX cartridge shells that have been modified to allow for the floppy ribbon cable.
The board is compatible with the standard TDC-600 firmware. Or, if using an imported machine in the US or UK, it can be used with the provided firmware which has been patched for the English Language.
The Original Source Code for the PCB, and a working disassembly of it, can be found here: https://github.com/jdgabbard/TDC-600-Source-Code
