Is that the same 2.8"? Mitsumi "Quick Disk" floppy used in the Smith
Corona Word Processor?
I believe so--at least the Famicom replacement drive belts work in the
SCM Mitsumi drives. It's been something like 30 years since I fooled
with the things (still have one in the closet) but I recall the
interface was very simple--power, one line to start the spiral
(controlled a solenoid clutch) and the read/write data lines.
I think the Smith-Corona got something around 60K per disk,but I'd have
to check my notes. Using the USART, it was very simple (this was before
cheap MCUs).
