Drive select - a choice of 1/2/3 - is determined by the programmable
shunt at location 1F. Installing a DIP switch is a much handier means
of selection. Configured for multiple drive installation, MX should be
open, HS shorted, and only the desired DSx shorted.

Termination is by a 150Ohm resistor DIP.

The power connector is the same as used on more modern 5.25" floppy
drives with pin-1 at 12VDC, pin-2 12V return, pin-3 5V return, and pin-4
5VDC. Pin one is identified on the component side of the PCB.

Sounds like a skillful add-on.
