This information came from the Apple Tech Info Library:

Floppy Disk Drives: Apple III Plus External Drive Adapter

The Apple III Plus has a DB25 connector for the external disk drive I/O port.
The standard Disk III has a 26-DIP flat connector on the cable.  To use the
standard Disk III with an Apple III+, you must acquire a Disk III Cable
Adapter. The service part number for this cable adapter is 655-6101.

Future Disk III drive cables will have a DB25 connector and will need no
adapter.

CAUTION:  Before connecting a Disk III to an Apple III+, be sure that pin 13
          has been removed from the adapter.  The pin can either be clipped off
          or pulled out. Later versions of the adapters may have this pin
          removed for you.

	Finding the official Apple made adapter is probably quite rare,
but the part number is above should you wish to hunt one or two down.
Somehow I doubt the Disk III ever shipped with a DB25 connector, looking
at Apple Canada's October 1984 price list, under the Apple III Plus accessory
list it states: "A3F0016  Disk /// with 'Plus' adapter". The entire III
line was disconnected six months before, so I doubt they bothered with an
update other than the adapter.
