I have my 11/40 fired up right now too.  I can load BASIC and I have a
 M9312 with a M7800 that returns serial signals/monitor running.  I have the
 CPU backplane, two core planes (empty), a DD11B and an DD11C.   I can
 operate without a grant card in slot, but I can't boot up using RL02 either
 way, still trying to track down if I have a UNIBUS issue.
 If there is something I can measure for you, for comparison purposes, let
 me know.  I will be around tomorrow too during the day.  I live near Phila,
 it's 845PM Tuesday at the moment here.

...slot 9 that is, system does not seem to notice.  I have only a M737, no
M787 installed but my CPU is not expecting a M787
