Well, 2.95MB or 2.81MiB.
That's w
2.8M runs at 1,000,000 bits per second.
Such controllers exist, but are not very common.
Can Catweasel/kryoflux handle that data transfer rate?

Speaking of the FC-1 boards: it appears that they support different sector
sizes, as well as MFM and FM encoding. How do you program this?

It would be a simple matter to upgrade a 1.44M backpack floppy with a
2.88M capable drive, as the controller is

Such controllers exist, but are not very common.

I'm interested, if the drives can be used for imaging 2.88 media (a la

I'm trying to gauge interest--I don't think he wants to sell them
onesy-twosy, but I'm willing to act as intermediary for single-unit
