power connection for 8" drive -- tandon tm848-01

I have an 8" drive that I intend to connect to a catweasel card for the
purpose of getting the bits off of a lot of old PT-DOS disks for my Sol
computer archive project. If I can accomplish that, then I'll extend my
Sol emulator to allow running PT-DOS on the emulator. Supposedly the
floppies have a lot of interesting stuff on them, including source code
to a lot of PT software.

After an hour of googling, I am unable to find what power to feed it.
The connector on the back is two 3-pin molex connectors and looks like this:

           +-------+
           | X X X |
           +-------+
           | X X |
           +-------+

Yes, the middle one of the lower pair is missing. I assume the power is
+5, -5, +24, and GND, maybe +12 or -12 too. But guessing isn't good enough.

Does anybody know for sure what power to feed each pin? I have found
information on how to build a 34-pin to 50 pin cable to mate the 8"
drive to the catweasel, so I think I have what I need there.

Thanks for any help.
