It might also be possible to use something like the SuperCard Pro or Kyroflux to copy the disk. As I understand it both use a standard PC disk drive and control it directly and do a flux level copy of any disk (i.e. read flux density from disk write same flux density to same place on another disk.) I have not tried either product myself.

Send me an address off-list and I'll mail it tomorrow. Conversely I would like a copy for TPDD myself if anyone is willing to either make me one, or trust me with mailing me theirs and I'll mail it back after making a copy myself. >From what I've been able to tell, although people have tried and failed for 30 >years, it actually *should* be physically possible to generate a new disk >purely from a download, as long as you have a real drive and a working special >cable.

A little progress has been made recently wrt recording the entire serial conversation during a backup, but it still has not yet gone all the way to being able to generate a disk from scratch from a download. I think the tools are there to at least work on it and eventually get there. So if you want an interesting project that hasn't already been solve at least 7 different times over the decades, yet looks within reach, there it is. :) You absolutely need a working TPDD or TPDD-2 drive to make these though, even if you use a modern pc to control it. It's not just a matter of an odd number of tracks or sectors or other formatting. The raw magnetic format is FM instead of MFM which all pc drives & drive controllers use. No amount of special software can overcome that!
