Starting to see the light at the end of the tunnel on my floppy drive controller refactor.
Of course after i'm done I will have like 100 different floppies to test to make sure I didn't break anything else.
My goal is to have several basic copy protection schemes working, and be able to boot all versions of Minix, with both the Tandy 1000 and PCjr able to read, write, and format floppies.

Adding drive sounds has already paid dividends, i've always felt that my PCjr floppy emulation was a bit too slow. I noticed that the JR was stepping slower than I thought it should. Turns out I had a bug in my Sense Interrupt handling, which was essentially causing the 1 second watchdog to have to expire after each Seek. That would certainly slow things down.
