What OS runs on what hardware?

I find the article's description of the etiology of the various versions of GCOS to be hard to follow, though admittedly Bull hasn't done any favors in creating the situation. Could someone clarify which version of GCOS runs on which hardware? We could start with just the current shipping versions (7 and 8) and current hardware. Thanks.

Name GECOS redux

I just took a look at some manuals from bitsavers. The first[1] has the title GE-635 Comprehensive Operating Supervisor but the text[2] uses the name General Comprehensive Operating Supervisor. Similarly, the next edition[3] has the title GE-635 Comprehensive Operating Supervisor but the text[4] uses the name General Comprehensive Operating Supervisor. In a Honeywell manual[5] the text[6] uses the name GE-600 Line Comprehensive Operating Supervisor (GECOS III). Given the above, what is appropriate to say about the original name? Shmuel (Seymour J.)

A further issue is that General Comprehensive Operating System#Historysays "The GECOS-II operating system was ....", but GECOS II came later; as of July 1964[2] it was still GECOS. Two sources[7][8] show GECOS I on April 1965 and GECOS II on November 1965. Shmuel (Seymour J.) Metz Username:Chatul (talk) 01:24, 7 June 2020 (UTC)[reply]

GECOS

After Honeywell acquired GE's computer division, GECOS-III was renamed GCOS 3 as heart of the 24-bits GE-400 series, and the hardware line was renamed to the H-6000 adding the EIS (enhanced instruction set, character oriented instead of word oriented).[31][32]

I would be happy to be informed otherwise, but I think this statement is wrong on several levels. I'm not sure GECOS ever ran on a 400 "The name GECOS was created to designate the operating system of General Electric's GE-635 system introduced in 1964. The acronym stands for General Electric Comprehensive Operating System."[1] Second, it was the GE-600 line that became the H-6000 systems.
