Joe Grana
Can anyone enlighten me on the history of AS/400? For example, in regards to
OS/400, when was
the first release? what year ? OS history?
Would highly appreciate it..
Second,
I am in the market for a used AS/400 system to practice my OS/400 v2rxx. Any
info ?

If you want to practice on an AS/400, check out WWW.TS400.COM You can use an
AS/400 over the internet.
I run it and right now you can try it for a month and then it is $25.00 (US
dollars) a month.

Search DejaNews for "history" in this newsgroup and check the articles from a
couple weeks ago with subject "History of OS/400". The initial post in that
thread included a fairly good history.

You should consider the book "Inside the AS/400" by Dr. Frank Soltis -- he's
one of the original architects, and relates an interesting history in the
first couple of chapters of the book.

code names were Silverlake and Olympic. OS/400 was basically the same as CPF
(the operating system on the System/38) except that slashes (/) were used
instead of dots (.) and the library came after the object.
Also, the new "Work With" commands started to appear (on the S/38 there were
no WRK* commands so DSPACTJOB instead of WRKACTJOB - if you wish to use S/38
commands, CALL QCL which gives you access to the S/38 command entry and CALL
QPGMMENU for the programmer's menu).
As far as second hand AS/400's go you should probably be able to pick up a C
or a D 9404 for a few hundred pounds.

The AS/400 and OS/400 were announced on June 21st, 1988. The predecessor to
the AS/400, the System/38 were announced in October 1978 but weren't shipped
until 1980 due to performance problems.

Origins of AS/400
IBM's top-of-the-line mini is little understood by the DP community at large,
but much admired by those who know it well. Compared to the competition, the
AS/400 is like an atomic clock in a sundial factory.
It gives the impression that IBM looked at the best of everything they had done,
and the best of everything all their competitors had done, and distilled it all
into one machine, the System/38, which became known as the AS/400.
At the hardware level there is a substantial difference between a System/38 and
an AS/400, but at the software level they are virtually the same.
The principal differences are in the use of command keys (the AS/400 has been
brought into line with SAA standards) and in the command syntax: System/38 uses
filename.library whereas the AS/400 uses library/filename.
Shortly after the introduction of the 360 mainframe, in 1964, the boffins at
IBM's laboratories began work on their next generation operating system, which
was intended to address all the shortcomings of the 360/370 family's operating
systems.
It was called FS (for Future System), but by that time customers had millions of
dollars invested in 360 and 370 programs, JCL and expertise. They would not
have been happy to have their collective boat rocked by a major conversion.
Somebody high up in IBM got cold feet and FS was killed off.
Another undercurrent became interwoven, because it was just at this time that
the US Justice Department made it's attempt to use the anti-trust laws to split
IBM in two. For some years customers found themselves called upon by two
competing IBM salesmen - a farcial situation which was unfairly blamed on IBM.
The top brass at Big Blue decided to hedge their bets, and FS was revived and
dusted off to give GSD the flagship it would need if forced to go it alone.
This was the System/38 and, despite a weak start, it was by far the most advance
machine ever offered by IBM. It is the ghost of FS which has risen to do what
it was origionally intended to do.
The System/38 was always something of a cult machine, and it was not until the
change of name to AS/400 that the architecture was really given the full benefit
of IBM's marketing power.
It is interesting to speculate where we would be now if FS had been unleased in
1978 rather than 1988..........
