IIRC, RS used pin 32 as drive select 3 (the fourth drive), although most
everyone else used it as side select for double sided drives. Since RS
used "missing pins in the cable" for drive select, and shorted pins
10,12,14, and 32 together on each drive, ...
If you used aftermarket stuff, it was no big deal. But if you used almost
all RS stuff, then it would require a jumper wire on the controller to
connect side select instead of DS3 to pin 32, a non RS cable, NOT using 4
drives on the cable, and cutting traces on all RS drives on that cable to
do drive select at the drive instead of in the cable (at least for DS3)
