This is a diagram of the jumper block and settings for the combo drive, showing how to set either drive to
be the A: drive and the other to be the B: drive--

If a time comes when those links don't work you can try emailing me at coastalnet.com and maybe I can send the one you need as an attachment. No guarantees. I'm not as good with software as hardware.

Floppy drives can (if equipped with the necessary jumper pins) be set as Drive 0, 1, 2, or 3.
In IBM PC type computers they're generally either D0 (drive A: ) or D1 (drive B: ).
For assembly line speed IBM decided to have all of their original floppy drives set as D1 and the ribbon cables fabricated with a twist near one end in lines 10 through 16 which turned them into lines 16 through 10.
This makes the drive connected by the plug before this twist look like D1 and the one connected by the plug at the end of the cable after the twist to look like D0 to the computer.
Thus, which drive is the A: and which is the B: is decided by where along the cable they are connected. Connected in the middle, they're D1, or B:, connected at the end after the twist, they're D0, or A:.
Newer drives may only have jumpers for D0 and D1, or perhaps may be permanently set as D1.
If you manage to get a drive connected "backwards" (plug upside down) the light on the drive will come on and stay on.
