Do you have a floppy disk drive emulator such as an HxC2001 or a Gotek? It is possible to use those with the 8" Tandy systems. I made a PCB for interfacing their 34 pin interfaces to the 50 pin host interface in the 8" drive systems:


You don't need my board, though. You can hand-wire an adapter cable if you would prefer, because no active electronics are needed. Even if you want to end up running entirely from real 8" floppy diskettes, an emulator is handy for initial bootstrapping, and for using the target system to copy from emulated images to real diskettes.

The same emulators can also be used with CoCo floppy diskette interface cartridges, though we have more convenient CoCo-native solutions like CoCoSDC, too.
