Absolutely marvelous work and documentation your doing. I particularly gleaned a lot of education from your 8" Floppy Drive effort.

I designed an IBM format compatible controller (FDC-10) for the Apple II back in the late 80's that allowed an Apple to read and write to FM & MFM formatted discs from CP/M and the up and coming IBM of the time. I had lots of fun doing so, but soon after focused on the DaynaFile that did the same, but for the Mac.
