A friend of mine just obtained an AS400.
It is a "9406-170 System S104V7NM Subsystem QCTL".
I know nothing of AS400s. He did say it boots.
So, what specs are this ? What does it run (OS ?, Apps ?),
and what can be done with it (he was originally going to use
it as an end table !!! until he found it actually booted).
The 9406-170 runs OS/400. I think it will run up to V4R5 of the OS.
OS/400 runs jobs segregated into subsystems, each tuned for their
particular purpose. Subsystem QCTL is the controlling subsystem from
which the remainder of the subsystems are started. When the system is
in restricted state (think unix init 1) you have control over all objects.
As for apps -- it's a business system. There are various languages
available, including RPG, C, CL, COBOL, Java and perhaps a few others.
I contend that Microsoft got many of its widely-touted-as-innovative
features in the .NET languages from the AS/400, as the Integrated
Language Environment (ILE) allowed you to seamlessly link between
various ILE/languages.
FWIW, there is a customized version of Apache on OS/400, as well as FTP
and TELNET servers.
