All WD-1006s?  I have two WD-1006-WAH and 4 extra Miniscribe 71 Meg MFM's
sitting around and my home system suffers from only 140 meg of storage.
Can I pop the other 1006 in and add two other drives?  If I have to cut
a trace or two, I need some detailed instructions since I have no manuals
for the controllers.

Does this apply with the WAH controllers?  Also, I never heard of the
WD1006VSR2 controllers.  What is the difference between 1006WAH, and 1006VSR2?
