I  need to control  two 10 Megabyte  hard disks  from  one  XT. The XT
already controls one 10M hard disk  using the original IBM controller.
I want to add one from an XT that is unused. I have  looked  at the XT
reference manual and the hardware and I can't see a way of controlling
an extra disk using  it.  I also  can't   see  a  way  of  having  two
controller cards in the XT without contention between them.

Can someone suggest either a way of controlling an extra disk with the
present controller  or  adding in a   second controller or  getting  a
different controller? Or anything else?
