Yup, that's all it is. The connector's a 14-pin DIN, which is
perhaps the hardest thing to find, but I may have one somewhere.
The pinout is as follows:
1 - Read data
2 - Side select
3 - Gnd
4 - Index
5 - Drive 0 select
6 - Drive 1 select
7 - Gnd
8 - Motor on
9 - Step direction
10 - Step
11 - Write data
12 - Write gate
13 - Track 0
14 - Write protect
You'll need a small power supply for the 3.5" drive, but a 5 volt
"wall wart" should do--and you can tuck two drives in the same box if
the mood strikes you. If you use a PC-type 1.44MB drive, make sure
that your disks don't have the high-density aperture uncovered (you
don't want the drive thinking that they're 1.44s).
