The AS/400 is still going strong. It's a virtual machine based on a
relational database (among other things), mostly programmed in COBOL (I
think the C compiler has sizeof(void*) == 16 or something like that, so
you can put a database position in that pointer), it doesn't know the
difference between disk and memory (memory is *really* only a cache), and
these days it's usually running on PowerPC hardware.
ISTR there's a gcc port for the AS/400. Oh, and it does have normal BSD
Sockets. These days, it's often sold as a web server.
Main customer base seems to be medium large businesses and banks.

Nope, the text user interface guidelines, a related but not the same
beast. That's where F1 == Help is from, by the way.
In fact, the user interface part of SAA was (is?) called CUA. And many IBM
text mode interfaces more or less follow it, including OS/400 (the os of
the AS/400). Once upon a time, I had the specs for CUA.

The first 386 PCs where not from IBM, by the way. Was it Compaq?

AFAICT, nothing ever was fully SAA compliant, though some systems were
more compliant than others.

That may be, but I believe the *concept* was invented in 1980 by Bill
Basham, with the Apple ][ DOS replacement Diversi-DOS (which was the most
popular of many versions to increase disk speed by about a factor of 5). I
still remember discussions how copying this stuff was actually the right
thing to do. Seems he's still in business as "Diversified Software
Research", http://www.divtune.com/.

The PowerPC was split off from the POWER architecture, and then the POWER
stuff was turned into the high end above PowerPC (with system prices about
a factor of ten higher as the lower bound).
IBM developed a version of OS/2 2.0 for the PowerPC, but *never* marketed
it - you could buy it if you knew the right number, but they never spent a
single cent on advertizing - by the time it was done, IBM had given up on
OS/2. Most OS/2 fans agreed that it was killed by IBM with extremely bad
marketing.
These days, of course Apple builds the most PowerPC machines; Motorola and
IBM produce the chips.
> Ummm... GEM was the Geos stuff?
No. GEM, I believe, originally came from CP/M. Most popular as the
windowing system of the Atari ST; given that someone did a quick-hack MS-
DOS clone to support it on the 68K, it seems fairly obvious that by that
time, it had already been ported to MS-DOS. (GEM-DOS is the only os I know
of that was actually worse than MS-DOS.)
Friends of mine (Gereon Steffens and Stefan Eissing) wrote a command-line
shell and desktop replacement for the Atari that was fairly successful
shareware for a while ... now how was it called? The CLI was Mupfel
(German for shell is Muschel, and there was a kid's TV character who
pronounced Muschel as Mupfel), and I think the desktop was Gemini. Another
(Julian Reschke) wrote *the* German Atari ST book. This was a fairly
prominent Atari ST area for a while, but somehow I never had one.

One might say it's time for X12, except the installed base of X11 has
become too large.
