ESDI Cabling

 The 34-pin control cable for ST-506 interfaces can either have a twist
 or be straight through where you need to alter the HDD drive selects
 accordingly.
 
 The 34-pin control cable used on ST-506 interfaces doesn't care
 whether it lives in a PC PC/XT or PC/AT environment.

 The AT MFM disk control cable (for ST506-like hard disks) certainly has a
 twist in it. This twist swaps over 2 of the drive select lines between
 the 2 drives, so they can both be set to the same drive number. I will
 have to get the manual if you want the exact details.
 
 I think the XT control cable does as well. I have an XT somewhere with 2
 ST412 drives (in the 5161 expanasion box) but I'd have to dig it out to
 check if the cable has the twist.
