Thanks for posting that the KT-11B documentation is available.
Does anyone know if schematics for it were included in the auction?
The flip chip board complement for it is in the posted document but nothing
else.
If the schematics are available, are there plans to get onto bitsavers?

Then perhaps that's what they are. They looked like tapes when I
looked at the business edge of the cartridge, that's why I called them
tapes. But

I've got a bunch of old stuff I want to get rid of. Much of it is
squarely on-topic here; most of the rest is tangentially on-topic, and
I hope the remainder can be forgiven.
All this stuff is in Ottawa, Ontario, Canada, and is yours if you come
pick it up. In theory, I could ship, but I suck at

That's the transport; but what are the shortcomings of the medium itself?
FWIW, I've got at least one DDS drive with rubber parts that have turned
