I was just looking for something a little simpler to add to the mix..

AS/400 (Application System 400) was actually renamed to:
AS/400 (Advanced System 400) and then renamed to:
AS/400 (Advanced Server 400) and finally to:
AS/400e (Advanced Server 400 for ebusiness) before being rebranded to:
eServer iSeries…..

Klas,

AS/400 Advanced Series was the full name of the server line introduced in 1994. Therefore, the long name was Application System/400 Advanced Series, and the line included an AS/400 Advanced System, an AS/400 Advanced Server, and an AS/400 Advanced Portable.

AS/400e is still an Application System/400.

None of these warranted a new picture on the history, since they were all AS/400s. It wasn’t until the iSeries that the community considered it a name change.

Angus, I believe the Advanced Series is when the transition from CISC to RISC occurred and that was a big thing, deserving some mention on your chart.

Bruce,

This particular chart is to demonstrate the branding of the platform.

If we want to get to the model level, a new chart could be created. There are definitely dozens of charts we could build to show the progression of the platform.

The IBM Marketing geniuses did tech folks no favors with these names. With the exception of iSeries, searching for employment opportunities is a nightmare. The slash in AS/400 mucks up a lot of search queries, and searching for i5 and i are absolutely useless. If your main marketability on the platform is RPG, you might have a prayer there of finding opportunities using that search argument.

Dan,

It is not the search that is the problem, it is the people who are POSTING the job openings. Until the community smacks recruiters around the ear, to get them to be consistent and current, we will have the same problem.

Unfortunately, it seems, we are all scared of recruiters..
