I'm planning on a USB controller, but I've
seen ISA projects that are
also
microcontroller based so I think it wouldn't be awfully difficult to
replace the USB data pipe with an ISA one.
Well just because you don't have enough to do please plan on an ISA version as well ;)
I think it really is time someone did a super floppy controller bringing together a number
of older technology on to one easy to use card (e.g. 8" drive support, copy
protection bypass, GCR reading) - all of this was available as separate products in the
past...
My friends think it's silly, and they're
probably right. =P
Hey silly things can lead to great discoveries:

Congratulations! Those are nice looking drives. The problem of course they don't work with anything
"standard".

Wow. That is going to be big endeavor.... A question what is your
target
system (i.e. are you planning on implementing
this on a controller
connected to a modern system w/ USB or are you planning on a nice ISA
card
so these drives can be used on older systems?) I
wish I could help
you
technically but my background is far removed from
engineering...
