Actually, if you are willing to set the drive jumpers yourself, you can run
a drive on any Tandy machine with a straight cable (no pins pulled!). 
I've used an old Model I printer cable (34 pin card-edge connector on both ends)
to hook drives up to various Tandy gear.
And Tandy *does* use a non-standard pinout on some machines. They used side select
for either drive select 3 or 4 (can't remember which now). But this only matters
on the Model 1....
