Believe it or not all the early PC's had the same cable.
The Amigas are actually correct it is the PC's that have it backwords.
The Amiga disk drive port is compatible with the Shugart standard. IBM screwed up when they made the PC and mixed up the two lines.
Since all early PC's were exact clones of the IBM They all had the same problem. So all early PCs had the same stupid twist in the cable. Later drive manufacturers added a jumper on the drive that would swap the pins so the twist became unnecessary. So all you had to do to make a drive Amiga or PC compatable was to move a jumper. In a cost cutting move disk drive manufacturers have since removed the swap line feature and the diskready line. Since PC's don't use them.
