Subject: Need 3.5" 40-pin pinout

I just got an IBM disk drive from a low-end PS/2.
It has a 40-pin edge connector and no power connector.
As some of the traces on the edge connector look MIGHTY
heavy, I guess it gets power from there.

Are the lower 34 pins the conventional 5.25" assignments?
What do the upper six pins carry?  39&37 are ground, and
   are tied to the same ground as 1,3,5..33
   35&36 are tied together.
The drive was made by Alps.

Many Thanks,
