That would work well if all the tape drives that use
the
floppy interface
followed the rules, but not all do. I guess it would be
possible to build
a board with some logic chips that could isolate individual
drives from
the bus, but I think it would be much easier for now to only
connect one
drive at a time.
Do you mean to say there are floppy-tape systems that ignore
DS? How do they work?

How about describing a few oddities for posterity?

How about two drives trying to be active at the same time if you put them

drive when you think the other drive isn't active? A lot of the old tape
drive software does not even report errors...

Today while unpacking some of the boxes from the move I found a Black
external drive NOMAI 540 and it's SCSI. It's uses a strange 12V power
supply connector and of course I do not have the supply that goes with
it.

Not very well? There were so many different companies producing so different drives, that I don't think I could even
begin to sum up all
the
strange things that some drives did.
