I don't know if CGOS supported multiple CPUs; a quick google didn't turn up any examples, but I don't think that there is any hardware reason why they couldn't. I don't think there is any difference in GCOS/Multics SCUs; later SCU models had more memory (Multics: Many Unnecessarily Large Tables In Core Simultaneously). Some of the IOMs had a "Multics" mode that enabled them to access the Multics page tables; it is not clear(to me) that that model was required for Multics; I am researching. -- Charles
