Together with
the info from Pete I am on the safe side to
turn on power.
BTW, I assume that you made a typo in the serpentine:
As shown it is correct. 2,3,5 on the left: 1,4,6 on the right.
it's one of the odder -11 backplanes. I believe the reson
for that odd layout is when cascading multiple boxes (BA11M)
the cables orient easier as option 5 to next box topleft is
the shown configuration and the REV-11 prom boot is nominally
in option6 as bus grant continuity is not required for most memories.
My source was the Microcomputer handbook 1976/77.
I also have one with core in it.
Allison option2|option1
option3|option4
option5|option6
That last line should be option6|option5, or ......?
