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.

I've seen suggestion that TU-58s are emulated
in simh on
PDP-11s. However, I'm not seeing it in a show dev and my
google-fu is failing me to find any info on how to use it. Any
pointers on how to boot from a TU-58 image?
TIA,

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).
