To connect a floppy to an embedded
system, I should have the pin descriptions, their
function and timing. How and what commands are
sent.
I can find the connector in my old projects from the 80-s,
I could plot them to a .gif or .pdf file for you - but I will
have to do some digging. Please make sure you want to
connect an old style FDD - it has no controller, you
need a NEC uPD765 or equivalent (well, there were
also other chips but this one made it through the years
in various IP forms), and write some code driving
heads/sides, implementing seek commands by counting
stepper pulses, etc. I did it twice during the 80-s, but
by todays standards this may seem too much work...
You may wish to consider one of these $15 or so
USB floppy drives they sell for notebooks, will definitely
be the easier to do option (I would guess they are like ATAPI
drives over USB, perhaps SFF-8070).
If you decide you really do need the schematics of my old
FDD interface which has the connector shown on it,
let me know and I'll start digging.
