Really great work...truly emulating a drive at the fundamental level will be of great use the whole vintage Mac community, especially as 1.44mb disks become more and more unreliable. I know that my "new" 3,5" floppies are a lot less reliable than the ones I bought in the 90s were.

Would you consider expanding your work to Apple II 3.5" and 5.25" drive emulation? I suspect that would be a significant amount of work, but they are based on the same lineage (IWM vs. SWIM, I know). And, the Apple II community would love you.
