I've had to suffer through emulating a disk drive also.  It's tricky
stuff, but I can help you if you need -- also I've updated my JACE
code to comment the inner-workings of the drive a little more so it
might help to look at an alternate implementation.  I updated my code
to speed up the emulator to max when disk reads are active, since
there's no possibility that anything else can be interleaved with disk
access and it would otherwise take forever (well, like it would on a
real machine)

Controller and I/O implementation

Drive implementation (deals with the emulated disk image more
directly)
