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. Allison
