Can anyone explain to me why the floppy drive cable being teared (twist?) at the drive end ??
Is that a mark for A: drive ?

Yes when the A and B drive was available it was designated that the A:drive was the first drive near the twist,so that is why the cable is split with the twist to ID first drive

The early floppy drives used hardware jumpers or switches to select which drive was drive A: and drive B:

As the PC evolved, the manufactures removed the switches, and added the twist to the cable to create a "cable select" system for floppy drives.

In a dual floppy system, the first connector from the motherboard end is the B: drive, then comes the twist, and the A: drive connector.

I actually have a floppy cable that has 6 connectors on it!
Controller (motherboard)
Tape Drive
B: 3.5"
B: 5.25"
A: 3.5"
B: 5.25"

Anyone remember hard sectored 8" floppy disks?
