- Pin 2 is out. It is the High/Low Density control pin. Touch a logic
- probe to pin 2 on the header at the controller while formatting a Low D
- disk, and follow it from there to the drive to determine WHICH device is
- broken. (If you don't have a logic probe a sensitive multimeter will do
- in a pinch). Levels are 0, +5. +5 should be high, 0 is for low, I
- THINK but don't hold me to it, and I don't have the book handy
