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 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. >> Later models also had virtual memory which I think used the MULTICs >> hardware.... No, I think GCOS had it's own.

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: http://bitsavers.trailing-edge.com/pdf/honeywell/multics/AM81-04_maintPrcds_ 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: http://bitsavers.trailing-edge.com/pdf/honeywell/multics/GB61-01B_OperatorsG de_Dec87.pdf http://bitsavers.trailing-edge.com/pdf/honeywell/multics/_58009997-040_MULTI CS_Differences_Manual_DPS_8-70M_Aug83.pdf are also interesting in filling in the history.
