PC Floppy Cable, was Re: MFM/RLL data recovery

[Curt at Atari Museum]

Nope, Drive A's require a portion of the cable to be flipped over, Drive 
B's use straight cable on most controller/drive setups... though I do 
recall what you're saying about the drive selects and such, I think on 
the old AT's with 1/2 height 5.25" drives you used to set the drive 
select and such... ah the dusty old memories in ones rattle-brain ;-)
