No ES/4381 models
This article misses the ES/4381 ESA-capable models. Martin Packer (talk) 10:22, 26 June 2008 (UTC)

Redirects?
Shouldn't there be redirects here from, e.g., 4381? Shmuel (Seymour J.) Metz Username:Chatul (talk) 18:38, 14 June 2010 (UTC)


 * At least for 4381, there now are. Guy Harris (talk) 20:31, 7 April 2017 (UTC)

CMOS?
Are these CMOS processors? When did IBM make the transition to CMOS? Gah4 (talk) 07:09, 8 April 2016 (UTC)


 * No, and "1994" according to IBM System/390 ES/9000 Enterprise Systems Architecture ESA family and "by 1995" according to IBM's "A Brief History of the IBM ES/9000, System/390 and zSeries" (they explicitly speak of the 1995 machines as CMOS, but don't say anything one way or the other about the 1994 machines).

Model comparison table.
The model comparison table has significant flaws.


 * 1) It doesn't use a consistent metric for performance, making it impossible to compare the various models.
 * 2) It lumps together model groups with different performance levels.
 * 3) It doesn't indicate which model groups support XA and which support ESA.

Also, it may be appropriate to cite announcement letters from the IBM web site https://ibm.com/common/ssi as sources for announcement and withdrawal dates. --Shmuel (Seymour J.) Metz Username:Chatul (talk) 19:48, 14 July 2021 (UTC)
