The tricky part is generating the recirculating bit

send as read data back from the simulated drive. It is expecting the
data that it just wrote to be in the data read back on the next
revolution. And you need one of these bitstreams for each head.
You only need to supply one track at a time--and you can hold off the
controller for any swapping you might need to do for a few msec. by
delaying the index pulse. An ST-412 track (surface) holds less than a
track on a 1.44MB floppy--it just spins 12x as fast.
I think it's probably quite doable if there's a market for it.
