This is another hardware question, concerning configuring a 720k drive
as drive B:

In trying various things out, I found the following:

I found a set of pins, which are marked DS and 0 1   2 3.
                                                 +++

The jumper goes as shown.  On my 1.2M drive, the same set of pins
exists, and I think it is for "device select".  I moved the jumper
to the 0 1   2 3 position.  I can't try it yet, but I think this is
           +++                                  drive B:.

I also noticed a string of positions for resistors, labeled
A B C D E F G H.  There is a resistor only on the A position.
Perhaps I have to move this to B for drive B: ?

If you have any information as to which of these is correct, please
let me know.  Thank you.
