   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.
