The schematic of the Apple controller is in the Apple DOS manual, but it may
not be of much help, as it requires a prom , the content of which isn't in
the schematic. You might check wiht Eric Smith, as I would easily believe
that he might have such information. The Apple controller, PROM and all
would, by the way, EASILY fit in a CPLD/FPGA, which might save no little
wiring, etc.
If you can't get this schematic anywhere else, let me know and I'll make and
send you a scan.

Subject: Apple Floppy Controller schematic - anyone?
Hi,
I'm currently designing and building a 6502-based computer system for
my
own use. Right now, everything is done. Except the
damn floppy controller.
I
read about the Apple floppy controller on the 'net
(woz.org) and I would
like to get hold of some schematics. Anyone got any idea where I could get
these? Better yet, anyone mind scanning and e-mailing me it?
Thanks.
