I installed 3.5" disks into my XT clone.    The only thing I had to do was
to crimp on a different connector onto the flex cable and make an adapter
for the power connector.   The pinouts are the same as a 5.25 but the 
connectors are different.   You will need to be running DOS 3.2 or higher
and I'm not sure if you need to be running any kind of special controller.
I'm running the Paterson Labs FLEX/FIXED combo controller.   Since it only
understands 2 flex drives I also needed to put a switch in so I could
switch between the 1.2Meg 5.25 and the 720K 3.5.    I still have a 360
in the A position.

Also, if you buy a raw drive like I did to install into your system.   You
will need to craft up some kind of mounting plate so it will fit one of 
your slots.    I'm more conserned with function than look so mine is 
sitting on the table out in the open. 

Again, this was on an XT clone, but should also work on your AT.    
H.B.
