Roger: This helps a lot. The CoCo drive I have is a single drive in a dual slimline case. I have to open it up to get the drive model numbers but at least now I have something to go on. On the cable, I would call Tandy National Parts. About 3 years ago, I ordered the DVI cable for the 102 and they had it. It was $30 or $40, but well worth it. They had bood disks too for $5.

If you put one of *these* drives in the DVI, you will most surely hear bad clunking noises when you try to format your first disk. The CoCo slimline drives came in 3 flavors: The FD-500, which was 35-track SSDD (bad) the FD-501 which was 40 track SSDD (which is OK), and the FD-502 which was 40-track DSDD (which side 1 will go unused, but should work fine). I have a DVI as well, but I don't have a boot disk or interface cable for my Tandy 200... so I have yet to use it. Hope this helps!
