I've seen suggestion that TU-58s are emulated in simh on

Using simh v4.0 from github, in the PDP11 simh ini file:
*set tdc enable**
**attach tdc0 tu58.dsk*
then assuming tu58.dsk is a bootable image:
*boot tdc0*
Only two units 0,1 are supported (just like a real dual drive) and the
images must be 262,144 bytes in size (like a real tu58 cartridge).
I remember TDC was DECcassette (TU-60).
The boot for RT-11 would be BOOT DD: the tape image should be built
with a DD driver or DDX for RT11XM.
Least that how it works for my physical PDP-11/23 RT11 system.
Generally all the files that should be on
a RT11 floppy needs to be on the tape.
For other OSs it first has to fit on the device and have a suitable
driver for TU58.

TU58 is really not much useful for running any real DEC OS other than XXDP, to
run diagnostics; that is what I use it for on my 34 and 44 (real hardware). I
don't use TU58 at all under SIMH (does not make much sense).
RT-11SJ works running from TU58, but just barely, and it is not really usable.
RT11 is barely usable once you move up to a dual drive RX02.
