I used a XT/286 this summer, and the only difference I could find between the
XT/286 and my own AT is that the XT/286 does not support a '0-wait state line' on
it's 16 bit bus. 

I haven't got the faintest idea about what this line is good for, but the manual 
for my Seagate SCSI host-adapter says that the jumper enabling this should be
installed when the card is used in AT compatibles, but this did *not* work on the
XY/286. I should perhaps add that it worked in my Sperry/IT almost-AT-compatible.
