I was looking for a device driver and when I didn't find it I
looked at SPD's an
TU-58 support wouldn't need to be in the kernel, it could easily run in
user space. Perhaps someone had written an application in user-space to

Here's a question for someone who has been around long enough to
remember.
Why did none of the available PDP-11 Unixes support the TU-58?

but I suspect if it isn't in 2.11 it wasn't in 2.9) and none
of them had support for the TU-58

Its a little more complex with a rubber wheel and its indented path.

Indeed. And that may even depend on the type of 'rubber' used and how
it deforms when pressed against the cartridge drive wheel.
I'd rarther get a bit of tube for my TU58.
