I've always assumed it was that, and thought it was a clever solution (admittedly, requiring unusual cable construction).

So presumably there is something like (_at the drive_):

01 - A
10 - B

(or vice versa).

Does that mean there is the _possibility_ of _four_ drives, using up the
00 and 11 options?

I reckon in a few years we'll have GoogleBum. You'll type in someone's name
and it will show you what their bum looks like. Even if they've never posted a nude picture, it will reconstruct their bum from bits of their face and leg
and whatever else they can find. - Charlie Brooker, RT 2014/12/13-19

This is an unusual way of doing things, and making cables like that must
be difficult. I'd think it would have been easier to just have a
jumper(s) on the drive, for either drive A or Drive B. But this is how
they did it back then, and how it will always be.

I am curious if 3 or 4 drives could be used. Not that I would need that
many. I'm still trying to remember if those ZIP drives connected to the
floppy cable, or to something else, like a serial port? I had one, and
at the time it was the only way to store 100 megs on one drive, which at
that time was a lot of data. I had one of them for a brief time, but I
found they were unreliable. Flash drives sure are a better thing, now.

The Zip drive installed in the PC I'm posting from is IDE. There were also external ones for the parallel port and USB.

As for the drives, I guess a lot of things are possible if you write
the code to access them from scratch. Whether this method for selecting
more than two drives would work may depend on the flexibility of the
floppy controller.

Ok, I had an IDE Zip drive, and I also had a parallel port one.
