Thanks. We'll let you know when a new response is added.

When the machine (a combination of the S/38 and S/36) came out, it was called the AS/400 or Application System/400, which was widely agreed to be a terrible name for marketing purposes.
Several years ago, IBM decided to rename its hardware architectures. The AS/400 was renamed the iSeries, the mainframe (S/390) was called the zSeries and their UNIX box became the pSeries.
More recently, the iSeries was renamed again as the eSeries i5.
The term AS/400 is still widely used to refer to the machine by users who have worked on it for many years.

Kristen, I'm not up on iSeries, so I'll leave explaining the functionality to the iSeries gurus on ITKE. But I can answer the first part. Back in 2000, IBM had an e-Server branding campaign and renamed the AS/400 to iSeries. Don't you love these branding cycles tech companies go through? Who can forget Microsoft and .NET on everything but the kitchen sink. Good luck and hopefully a real iSeries guru will stop by and answer your question on iSeries functionality.

Well chaps, in actual fact, IBM stopped selling iSeries in 2006. :) The current server sold is the 'i5'. The most recent server was the 'iSeries' - circa 2000 > 2006 and the oldest generation of this server was the 'AS/400' but correct not been sold since 2000. (And of course S/38, S36 before that). So to make things clear as mud.. 'System i' is the brand name, 'i5' is the server.. which runs i5/OS (used to be OS/400) as its OS. Isn't it time we stopped using the term AS/400, it sounds so old and dated!
