Hi, hardware people.  I need some info about the 360k floppy drives in
my Z-158.  The B: drive is flaky, and I wanted to swap A: with B: to
make sure that it is the drive that's at fault (rather than the
controller or something).  I believe that there are jumpers on them to
indicate which is A: and which is B: but the jumpers are unmarked, and
quite different between the two.  General information about jumpers for
A:/B: would help a lot.  I could also use specific data about the
drives...

One is a Panasonic/Matsushita, with the numbers "JU-455-5 ACG",
"FMD00790B4", and "JVC SS01FF" on it.  The other is a Magnetic
Peripherals/Control Data drive, "ID 9428", "PN 77740012", "LOT H-8519".
The machine came with one drive and the other was added later --- I
think the Control Data drive was the original one, although it's the
B: drive now.

Any info would be appreciated.  Oh, for what it's worth, the drive
problem is that it has *much* trouble reading sectors on the innermost
tracks.  Lots of "bad sector" errors when I format a disk, although the
same disk will format fine in the A: drive.  (Following up on a previous
posting of mine, it appears that I can drop in a 3.5" 720k drive with no
problems...)
