It's a mini. suggest you try a site starting with www.ibm.com ...
The IBM System i (formerly known as iSeries, AS/400, and Application System/400) is a minicomputer platform produced by IBM. It was officially introduced as the AS/400 in 1988. It was then renamed to the eServer iSeries in 2000 as part of IBM's e-Server branding initiative. In 2006, the platform has once again been renamed to System i.

Well its a big black ugly computer with a funny keyboard and a 1980's porno looking screen. Depends on the size of the setup though.
Its a --->little<--- bit like Windows Terminal Services or running something like Pine on Linux via SSH.
Users use terminal software like powerterm to connect to the AS400. From there the user has access to the highly customized software designed for special tasks. The "look" from a user perspective is a very outdated menu driven interface with no fancy GUI eye candy.
It is however very functional and its amazing how fast people can get work done on them as the menu's/input needed becomes very predictable after a while.
Dont really know how to explain things but I may be able to give you some answers if you have specific questions. Worked on one for more than 2 years.

This is were Systems start - like in System 36 - terminals with 501 errors - and knowing windows don't mean jack
so true!

Hope this helps clear things up a bit....
The AS/400 (System i) is a very secure and stable server running on os\400 with an integrated Database (DB2/400). It is widely used in the Banking and insurance industries in South Africa. Although it can run programs written in Cobol, C, C++ etc, the main programming language is RPG. It's main interface is via a 5250 terminal emulation via PC or dumb terminal. The interface is normally menu driven for users, but programmers\administrators have command line access (Unix like). Custom written GUI interfaces may also be used, connecting to the database via ODBC. It utilize 64-bit processing, main storage and memory as well as processor power can be added on as needed. System-sizes varies widely, depending on it's intended use. Some companies utilize it as their main database server, others to run their internet banking sites or for their ATM networks.
Most companies prefer to write their own custom-made software for the AS\400, from there all the jobs requiring AS/400 knowledge\programming skills. Allthough RPG is not a very difficult language to learn, there's not a lot of RPG programmers in South Africa.

No its not difficult to learn but its absolute HELL to try and decypher someone else's RPG programs.....

Most RPG code I've seen is relatively straight forward, but there is always developers trying to be smart, saving nano-seconds on processing but losing weeks on the maintenance side.
