I only ever had my hands on the one in my old VAX. They were available
standalone, but pricey.

What's the problem? Rollers turn to goo? Electronic failure?

There is out there a TU-58 emulator for PeeCee. I've seen it and I've always
wanted to put one together, perhaps with a floppy drive so it would be possible
to still swap media, after a fashion. With the things I've been playing with
in the modern hardware arena, I've also contemplated taking the emulator and
sticking a modern CPU in one of these encyclopedia-sized cases I have and
adding a text LCD display on the front and a couple of buttons (though the
joystick port) and building up a virtual tape library. The ultimate
incarnation would be able to hang a _real_ TU-58 off of it and be able to read
and write _real_ tapes as well as act as a cache/jukebox. In that form, it
would make a nice standalone backup device for DECtapeII.

Got a drive I can borrow in a VT103, got hardware, got the RSP spec (Radial
Serial Protocol), got tapes. Don't got time. :-( It's been on my fantasy
project list for ten years and has managed to only move _down_ the priority
list since then. Maybe when I dig that 11/730 out of the storage locker...
