I wish to publicly retract my comment that the 1000-TX has an AT style
expansion slot.  It doesn't, as numerous people have pointed out, and
it serves me right for confusing engineering prototypes with the real
thing.

Sorry for the confusion...

Now you know why they don't let me design hardware.

Now for some better info on adding Hard Drives to the 1000's ...

Up until the 1000SL and 1000TL, all Tandy 1000's shipped using IRQ2 for the
hard drive interrupt.  This was done to remain compatible with some IBM
PCjr video routines ( strange but true ).  The SX and TX have a dip switch
on the motherboard which allows you to swap the interrupt to IRQ5 ( switch
S-1 position 2 should be switched to off ).  The Tandy 1000SL and 1000TL are
shipped with the more standard IRQ5 for hard disks, and have a jumper on the
motherboard in the rare case that you need to run the aforementioned IBM PCjr
routines.

The above information I think is true, but as you see by my track record
if you really need to know, call Customer Service.
