In looking at our  collection of  panels  in front of us,  the  large group 
of smaller and   large black panels  seem  to be the same between all op 
sys  however.   On the   main panel - yes the difference is the APU  lights.  
As  I  work  though the volume of  stuff in warehousing will have to keep an 
 eye out  for one  with  APU.
 
Would  all the  processors  have  APU on the panel  or  just  some of them 
in a cluster ( if that is the correct  term)
 
So the ones on the surface here   were probably running  GCOS  or  CP6 (The 
Big H that thought it was a Xerox Sigma...) 
 
For me that is a closer personal tie since I had a GCOS account I   would 
occasionally 'Play'  with.
 
Looking at all the panels in the publications below is  really a brain  
whack  compared to the   full maint  panel I  have   for series II series III 
HP-3000  that neatly fits in a  suitcase I can carry under one  arm.. ( I 
guess I had it easy!)

Yes and no, is my impression.  I got the impression from my recent reading
that the addition of the  Appending Unit used to create the Multics 
segmented
memory meant changes  throughout the CPU, so that in any line 
(Multics/GCOS) a
CPU could be field  upgraded, but one couldn't upgrade from one line to  the
other.

No, I think GCOS had it's own. (The Multics one was  complex, a lot more 
than
GCOS needed.)

Good  point.

Thanks for that pointer! I don't know why I hadn't thought of  looking for
Honeywell CPU manuals, that should have been  obvious!!

Anyway,I found several with useful bits, especially this  one:

Nov86.pdf

which  does illustrate a number of the panels. From which it's pretty
conclusive  that these aren't Multics CPU panels (sigh).

These  two:

are  also interesting in filling in the history.
