Well, I found a couple of 3.5" drives that can be jumpered, and the
Altos doesn't recognize 'em at all. I suspect it wants a drive that
does DD only.

Do you have the jumper settings for that? TEAC's documentation
drives me up the wall. I have an FD55GFR that I can make boot and read,
but not write or format. I suppose if I absolutely have to, I'll rob an
FD55GFV from the 11/53 - the -GFR should work fine on the RQDX3.
