Minicomputers
 ecent
experience (except for the last three or four years being back with mainframes) has been with midrange computers (formerly known as
"minicomputers") and, more specifically, with the IBM AS/400.
These boxes have exploded in popularity both because of the recent advances in
power (especially since the RISC processor became available) and with their
built-in support for everything from DB2 to the Internet. The table below is an outline of my
exposure in this area.
Hint: Don't believe all
the hype that these boxes don't require an Operating Systems Programmer — you'll end up
paying somebody quite a bit every time you try to take advantage
of all the "neat" things it supports. J

Installed and
maintained several releases and levels over about a five or six year
period. I even had the "fun" of upgrading to a RISC box. |

Thankfully, I had only
about a year to deal with a S/36; but, it was enough to get pretty
familiar with its ways before having to migrate both it and a mainframe to
an AS/400. |
