From the Quantum Q200 series technical reference manual (81-45528),
look at the printed circuit board on the drive and identify 3 jumpers
labeled A2, A1 and A0. The 3 plugs establish a 3-bit binary number
with A2=4, A1=2, and A0=1. With no plugs in, the address is zero.
If you don't have any spare plugs, you can steal the one from location
P1. This plug is provided for just this purpose, and has no function.
