Sadly, the AS/400 line (iSeries) is slowly dying off ... IBM can't
market it's way out of a paper bag, and the 'cash cow' status the
machine has had has caused it to fall too far behind.

Not anymore, with the change to PowerAS some years back. The original
AS/400s were more odd in the hardware sense.
The whole concept of single level storage is amazing in that works at all.
