You might want to consider an SVD. There was a run recently of them.
They plug directly into your controller and mimic the drive. And they have
an interface to transfer files to/from PCs. I have an original around here
somewhere.
And I'm sure some of us have spare DD floppy drives. Are yours single-sided
or double-sided? I have a couple of pulls from my Model 4P that were
single-sided half-heights. So you could put two in one drive bay and
something else in the other.
You can always go 3.5", too... Sure there is a faq with this stuff
somewheres...
