I think that the PDT-11/150 should boot a regular RT-11

Nope! The RXT11 controller is annoyingly not quite compatible with the
RXV11, even though it's generally similar. So the PDT boot disk needs
COPY/BOOT:PD RT11FB.SYS DX0: (supposing you're making it on a typical
11/03 system) since the DX: bootstrap and driver won't work. The
monitor (SJ or FB) *is* vanilla though.
I've got a triple boot block (DX:, DY:, PD:) on
ftp.dbit.com, but I suppose
it's too late to go back in time and fix this silliness! :-)
