This is a bit of a long shot, but is anyone aware of a successful
method to read IBM Selectric MT/ST tapes?
A museum in Australia has a box of them and are interested in the contents.

I would have assumed a typo, but as I get deeper and deeper into IBM,
I'm finding more and more System/### than I ever heard of. So there was
a non-trivial possibility that's

Is the S/260 a system that I'm completely oblivious to? Or is it a typo?

I would think that an engineer would realize that the glass is neither
half-full NOR half-empty; it is merely that the glass was spec'ed with the
wrong size.
Yes, I am too cynical to be in marketing.

One of the shortcomings of the MT/ST when compared to word processors is
the lack of a good "mailmerge" option. You could code a stop code on
the tape, where the typewriter would allow for manual fill-in-the-blanks

Yep.
And, it was not appreciated when I suggested an interim release between
the MT/ST emulator and "Full-ST" to be called "Half Full ST"

A link I forgot to include that gives a flavor of how the tapes are used:
https://files.eric.ed.gov/fulltext/ED112083.pdf
Curious thing is that was no take-up reel on the MT/ST; the 100 feet of
tape simply was ejected loose and later rewound back into the cartridge.

Sadly, whoever cataloged this had no idea it was for IBM MT/ST tapes
so there is no mention of MT/ST in

I'm fairly involved in the global Selectric community and while 1 or 2 MT/ST’s
exist, they’re non-functional.
