Looking from the back, there is a set of 7 positions for shorting
blocks next to the power connector on the servo PWA, and another
group with two positions on the data PWA.

From left to right, the options are:
1. Parity check option
2. motor start option
3,4,5 BCD logical drive address MSB is leftmost jumper
6,7 ground select jumpers

On the other set, think of the bottom left pin as a pivot.
Vertical position is for terminator power from disk drive,
horizontal position is for terminator power from cable.
