[comp.sys.mac] Swapping Floppy Drives - Help!

thecloud@dhw68k.cts.com (Ken McLeod) (02/11/89)

 My internal 800K floppy drive bit the dust (the ol' head decapitation
trick), and I thought I'd be clever and swap my Apple *external* floppy
drive into my Mac to replace it. However, the drive doesn't seem to
be able to read & write when connected internally (it is recognized,
though). I was told that something needed to be fiddled with (two wires
cut, I believe) in order for an external floppy drive to be used as an
internal drive, and that there *might* have been an article on this in
a past BMUG newsletter.

 Does anyone have any experience with this, or know the correct procedure?
(This is on a 2 MB 512E w/SCSI & XPRAM, by the way.)

 Thanks a heap...

In replacing the 800k floppy, there may be some wires to cut.  The problem
can be noted by constant movement in the drive.  The internal cables with
the yellow stripe should have the wire cut or in many cases, the wire is
actually missing.  That is, the wire is solid plastic and has no wire in it.
Also, it has nothing to do with the fact that you had an EXTERNAL drive
but that there are different versions of the drive.  Assuming you have the
old cable, and your drive displays that symptom, you can cut the wires.
Counting from the stripe, cut the 9th wire, and the very last wire.  As far
as I can remember, it is not necessary to reverse this if you go back to the
other version drive. Good Luck.
