Infobox formatting

Figured I should add a note to apologise for my rather ugly fix for the way the infobox in the architecture section is rendering the surrounding text. Or mainly so that somebody who's less clueless about infobox markup than I am might do it properly. :D --Vometia (talk) 10:45, 28 June 2020 (UTC)[reply]

Cutoff point for S/370 compatible?

At what point should new or specialty processors no longer be listed in #Models sorted by date introduced (table)? In particular, should the box include:

-155 II
-165 II
9472
P/370 card for PC
R/370 card for RS/6000
P/390 card for PC
R/390 card for RS/6000
Multiprise 2000
Multiprise 3000
9672

Architecture details

If "IBM documentation numbers the bits in reverse order to that shown above", why not reverse the position numbers to agree with the documentation? Peter Flass (talk) 17:25, 28 June 2020 (UTC)[reply]

@Peter Flass: Something like this?

@Peter Flass: I've added PSW layouts through S/370-ESA; the tables could use some tweaking. Shmuel (Seymour J.) Metz Username:Chatul (talk) 15:41, 7 December 2020 (UTC)[reply]

What is "the successor"?

The term successor might refer to immediate successor or to final successor, but the article lists ESA/390 as the successor, and it is neither. The sequence of architectures is listed below; the successor should be shown either as 370 XA or as z/Architecture.

System/370
System/370 Extended Architecture
Enterprise Systems Architecture/370
Enterprise Systems Architecture/390
z/Architecture

Also, 390 ESA is *NOT* a renaming of 370 ESA; it includes new features. Shmuel (Seymour J.) Metz Username:Chatul (talk) 02:22, 16 October 2020 (UTC)[reply]
