	Could some kind soul please send me (or post) the correct
connections for an external FDHD to the DB19 on the back of the Mac.
Apparently there is some difference in pinout between an external
and internal FDHD, getting them confused fries the hardware - I know !

	Specifically I have replaced the (broken) mechanism in my
external 800K drive with a new FDHD, but I want to plug this into
my Rapport box - I believe that some of the wires must be crossed
to tell the drive that it is external and that it should not
respond to signals meant for the internal drive.

Ps: the cable that comes with the 800K drive is short a few critical
wires, -12V for a start.
