floppy drives and cables

The twist swaps the signals, so that one connector can have an A personality and the other a B personality. (Just like a CS Cable Select method.) [] 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? 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. |
