The 765 does not provide the ability to perform raw track reads/writes
like the WD devices do ...
I interface with the FDC via direct hardware I/O to both the FDC itself
and the DMA system.
At some point I will tidy up the source code and make it available, however
it is written for my own Micro-C 16-bit DOS compiler, and makes use of my
own screen/windowing library - it would take a fair bit of work to port this
to another system, but someone with enough spare time could take advantage
of my "learning experience", and re-implement the algorithms under Linux or
some other system.
