I found a device among my TRS-80 stuff that I can’t identify. It’s some sort of floppy controller, but in a blank case. It’s got an FD1793B-02 chip socketed in it, and 40-pin and 34-pin card-edge connectors on each end. Solder side of the board has “8709203 Rev. B” on it, but I can find no reference to this online anywhere. Anyone have a clue?
