... response to item as MOVE- NOT a MOVE, it was a 3 way merger: IBM calls it Triadic
It was absolutely not a move at all.
On the exact same day, IBM said, in 3 different annoucements:
(1) _System/390 Announcement_ "IBM today introduced System/390... System/390 introduces the IBM Enterprise System/9000 family of 18 new processors ...
(2) _Enterprise System/9000_ " Based on IBM's Enterprise Systems Architecture/390 (ESA/390), the IBM ES/9000 family offers users ..."
(3) _ES/9000 Characteristics_ (subhead System/390 ES/9000 Processor characteristics) "The IBM Enterprise System/9000 (ES/9000) family of 18 processors announced today for System/390 ..."
Now which is the left head and which is the right head of what IBM termed "dyadic" for a prior generation system with two processors, the 3081. Is 390 what opticians call O.D. (D=Dexter, the major one) for right, and 9000 what they call O.S. (S=Sinister) the left)? Since 390 is what survived, actually being called S/390 (and that's what they put on the system box), 390 is the first name
on the article.
Since most of the models that followed were 4 digits, starting with a 9, 9000 is the second name.
For reasons too lengthy to explain in this brief (lawyer's style "brief") explanation, the top of the article was focused on the Air-vs-Water cooling, since Amdahl had already patented its air-cooling a decade prior. This info came from 3 sources: non-Wiki writeups about Amdahl, the 390 article and the 9000 article. MERGER - not a move.
The 9000 article was identified by the now-RedLined Angusus as "Created page with 'ES/9000 is the family of processors developed
to accommodate System/390-based operating systems. Hardware features new with the ES/9000 family of processors)"
Angusus - made 3 more edits that day (17 Sept 2007) and, that's it.
Kubanczyk - made 5 edits that same day, then one more a month later.
Other edits aside from mine were mostly one edit, as follows.
Robertgreer one edit, Rjwilmsi one, Hellisp one.
Bumm13 two edits, Malcolmxl5 one, Dawynn one, Jake Wartenberg one
Rwessel made one edit, 3 were bots, one anon,
I made the last 6 edits.
Kubanczyk made 11 edits in the 390 article (vs 5 in 9000), Robertgreer made 2 edits in 390, one in 9000. Rwessel and Bumm13 made none in 390.
Guy Harris, a heavy contributor to Mainframe articles, made 25 edits in 390, none in 9000.
As for the time line, 390 began as a 6-sentence article (by anon) and had edits each year since. 9000 began 2007, with no edits in
2008, 2010, 2014 or 2016. I made 6 edits in 2017.
The "Edit Summary" of the initial 3-way-merge said "initial article, new material plus ESA/390 & ES/9000," thus giving the names of the 2 Wiki articles as well as mentioning that there was new material. It was the lack of seeing an easy to integrate this new material into BOTH articles, and leaving them as parallel, plus the realization that it was necessary to build on IBM's own same-day 3-part introduction, that had to be addressed. To make this all more clear.... — Preceding unsigned comment added by Pi314m (talk • contribs) 08:48, 16 February 2017 (UTC)[reply]

This page currently says S/390 is the fourth generation. S/360 is presumably the first generation; what are the second and third generations? Guy Harris (talk) 19:58, 18 October 2020 (UTC)[reply]
The article currently counts from S/370. The mainline is
In fact, it was only the parallel (bus and tag) channel that was "in the System/360 tradition". The channel subsystem was introduced with S/370-XA[1] and performed queuing previously performed by the OS. Also, the name in IBM publications is simply Channel Subsystem, without the term 'I/O.
