Hi Ashley,
Good enough.
FWIW, Guy's program decodes to the following:
001000 005000 CLR R0
001002 005200 1: INC R0
001004 006100 ROL R0
001006 000005 RESET
001010 000775 JMP 1B
The instruction of interest is the RESET, which sends an INIT to
the UNIBUS for 10ms. It must also have the effect of displaying
the contents of R0 in the DATA display, or perhaps whatever register
was last referenced. I figured that there was an instruction which
would behave in this manor, but did not recall what it was...

Tom,
Thanks for decoding it. I had planned to pull out my 11/40 handbook
and do that as well, but haven't gotten around to it. After getting the
machine running smoothly and booting several various bootable packs,
I decided to take the rest of the night off.
