The external drive he is referring to has the standard 3.5 4 pin plug (internally) and all it needs is an adapet to the larger 4 pin used on Coco 5.25 drives. The ribbon cable should be fine, it just needs a 3.2 connector pressed on.

I had one of these drives and it took me about  15 mins to hook it up. You just remove all the T-1000 crap internally, then it's a standard 3.5 drive with no power supply.

The 4 pin connector (many Tandy 1000's did not have one and shunted power

through the ribbon cable.) should be the standard 3.5" floppy power 
connector.
A picture and model numbers might help identify the drive.  On 
the Tandy floppy
drives without the 4 pin connector some of the ground lines 
carried the power
and traces needed to be cut and power lines tapped in. 
Not an easy project
unless you are proficient reading schematics and/or 
tracing PCBs.  I converted
one 720k 3.5” Tandy 1000 drive about 20 years 
ago and would not bother doing
another.  Although 1.44M 3.5” are getting 
hard to find nowadays.
