Interesting archaeological dig. Are you able to post the .wav files of the cassettes?
"DS" error is, in my experience, what one sees from garbled data (like a serial line without XON/XOFF flow control). I believe it technically means, the m100 saw data it recognized, but it didn't see a line number first, so it must be a "Direct Statement". So, that could mean that the cassettes are corrupted or perhaps were recorded on a cassette deck that was out of alignment. (Homebrew tapes might need to be played slightly faster or slower.) But I think that corruption is unlikely. Does the DS error happen at the beginning of the program? If so, that'd imply to me that it's not a BASIC program at all. Or perhaps, as you suggested, it is a tape from a different machine architecture. I don't have a cassette deck, so I don't have any experience with it, but I am surprised that the file is not loading in the TEXT editor using F2 (LOAD) CAS: as I had hoped that that would be able to load any file, even a corrupted one. Perhaps the M100 cassette format keeps a filetype (similar to .DO, .BA, .CO) and TEXT will refuse to read binary files. —b9 On Fri, Nov 25, 2022 at 7:48 PM Jason White <[email protected]> wrote: > I just bought a few tapes on eBay, gambling that they may have some > obscure software on them.

Does the Model 1 use the same .do that the 100 does?
