I am interested in obtaining as much technical information as is available
for the Uni-disk 3.5.  I am particularly interested in how its formatting
differs from the 5.25 floppies -- such as how many sectors/blocks per track
and how many tracks per side.  I made an attempt to disassemble the boot code
on the 3.5 controller but it didn't take long before it went beyond my meager
understanding.  I have not seen any published works detailing the innards of
this system such as was done by Quality Software for the 5.25 drive in 
Beneath Apple Dos.  If anyone is aware of such a work I would appreciate a 
line on how to get a copy.  Also, if anyone has heard of efforts to develop
a nibble copier for the 3.5 I would appreciate info on that as well.

Thanks in advance,

Eric S. Ford
