Well, the problem may be that some time before the SE and II came
out they changed subtly the design of the drive.  I know this happened
because I went to get an accelarated 512e fixed and they said that
they could not swap the drive because the new drives required a new
cable (different than the old pinout) and that they did not have that
cable in a sufficiently long form to get around my accelarator
(A custom long drive cable of the old style had come with the card).

So if your drive is one of the older ones, and you are using a cable
for the II (which is designed for the new drives) the pinouts are wrong.

I know new drives will work in old systems given the proper cable.  I
have no idea whether old drives can be made to work in newer systems.

If you get an answer I'd love to hear as I have been considering the same
process to give my II a new floppy.
