The problem with GCOS is that there isn't a history I know of that it 
was anything but Honeywells property.  A lot of negotiation and 
persistence on the part of many folks went to getting it to where the 
Multics code could be released.  And it was lucky to be saved @ MIT and 
the CHM with  donations.

I don't know of anyone with GCOS when it has been mentioned over the 
history of the discussions about this hardware.

Many thanks to Harry and Charles for writing the emulator, and to the 
others reviving the system.

I plan to have a 6180 panel at VCF West and an original 645 board from 
the first Multics system for show and tell.
