Is the ROM image you're working with a real GT40 ROM, or was it generated 
by assembling the version from the manual that was mentioned somewhere?

As soon as you've got the ROM image into a form that the LOAD command 
will load as you need it to, please send it to me and I'll build it into the 
simulator and let be used via:

     sim> set vt enable
     sim> boot -40 vt
since:
     sim> boot vt
already runs the Lunar Lander demo

Under the covers, the "boot -40 vt" will configure the DL device to the correct
CSR address and the appropriate vector.
