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.
