Apple Floppy Controller schematic - anyone?

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.
