I recently picked up a 386-based ISA SBC and a 3-slot backplane to do
exactly this. The whole thing, less actual floppy drives, should run on
the PSU from an external hard drive enclosure, and just about fit in a
standard 2-bay 3.5" drive enclosure.
The big win, which is doubtful, will be if the SBC's FDC can do
single-density. If that turns out true, I don't even need the backplane.
Alas, that "free time" thing has been a problem lately, so I haven't
touched this in a month, or even tested the 386 yet.
