Does this count? I named it bill because I wasn't sure which version it was
:)
And I did it from tape, not RX-50s and swapping 31 of them in/out with
simh... And I couldn't get 11/73 to work (I think my simh has a regression
there), but 11/83 worked just fine.

But I did something wrong... It prompts me for the load device on each
reboot.

sim> boot rq0

Sizing Memory...

Boot: rd(0,0)unix    (CTRL/C will abort auto-boot)

Load device (? for help, <RETURN> if none) < ht tm ts tk rx rl rc > ? tk

(and I think my simh is a bit wonky because it doesn't quite work: it hangs
from time to time, but only after a reset)
