The original Tandy drives were normally made by a
company called 'Texas
Peripherals', and are identical to Tandon drives.
They're both actual Tandon drives, dated from 1981.
Start by taking them apart a little way.
Unplug all the cables going to the PCB on top of the drive, take out the
2 screws and slip off the PCB. If there's a separate motor control board
on the back (old drives have this), then remove that as well.
-Cable to connect external drives to the
computer.
That's easy to make. It's just a length of 34 way ribbon cable with edge
connectors crimped to it. Most people these days don't pull pins as Tandy did, but instead select the drive using the links on
the drive PCB.

I did this to one drive, and got it working, but the other is beyond
repair. A penny was once dropped into the computer by my friends 4 yr. old
cousin. The penny landed on top of the top drive PCB, shorting some stuff
and fusing the penny to a few components. I need at least one drive.
-Internal
cable connecting RS-232 adapter to the main board.
If you're _really_ stuck for this, remove the connectors from the CPU
board and RS232 board and solder some 0.1" SIL headers in place. I seem
to remember it's 20 pins. Then use a 40 pin (or whatever) IDC ribbon
cable + connectors (like a very short IDE cable) to link them up. Just
use the same row of holes in the 2 connectors.
