As the (second) owner of the first TRS-80 Mod I sold in the State of Maine,
(and more to the point, as being long ago in the business of manufacturing
floppy drives) I can assure you that this is not so.  To the best of my
knowledge no 10" floppy drive was ever manufactured by anyone.

The Mod I had optional 5 1/4" floppies, (originally single-sided, single
density, 35-track Shugarts which cost $400 and held -- wait for it -- 87
kilobytes formatted).

The Mod II had a single built-in 8" drive and I think you could get an
external for $$$$.

The Mod III had one or two internal 5 1/4" drives, IIRC.
