I beg to differ 
However: when we bought our TRS-80 in 1982 (used, from my cousin) the thing was already about 3 years old. There was still someone running a business selling this software, on cassette (& from whom we bought some of the software in these photos). You’re right, of course, as by then we were outliers - but a year later, Radio Shack’s Computer Center stores - which had otherwise moved beyond the Model 1 - were still selling some software on cassette (heavily discounted, by then).
(I’ve previously mentioned how we paid someone to (sort of) upgrade it)
Come to think of it, for Christmas of '83 we still could (and did) buy Supreme Ruler on cassette.
And it wasn’t until a year or so ago that I finally found out Dante’s Inferno would suddenly end due to a bug.
