Not quite. The S/390 Integrated Server was a VERY large, VERY heavy
Pentium-based PC. (well, large and heavy "for a PC") It contained a
P/390E board and was shipped pre-configured and ready to roll as a
full-blown mainframe with really crappy I/O performance. It is a
deskside box that weighs about 350lbs.
Incidentally, the Multiprise 3000 looks almost identical, but it is a
"real" mainframe. It's an S/390 G5 in a small box with
partially-emulated I/O. Its I/O performance is nowhere near a
full-blown S/390 G5, but it was sold at a fraction of the cost, and is
still a pretty good performer for light-duty production loads. I have
one of these that I've not yet managed to get running; a lot of
unobtainable software is required to bring one up. Operating systems
are (ahem) not a problem, but there's some MP3000-specific
initialization software that is tough to get, that I've not yet been
able to locate.
That's the second one I met in a very long time. I would say they were
not as popular as the crowd you described.
That's because they were gigantic, overpriced PCs with P/390 cards
installed in them. ;)

There still are. ;) There are three types of P/390 cards. The first
is a card for the Microchannel bus, and it has a relatively slow S/390
architecture processor on it, along with 32MB of RAM, expandable to 64MB
or 128MB. The second P/390 has the same CPU, but is a PCI card, and it
comes standard with 128MB. The third is the P/390E, which has a much
faster CPU, and has 256MB of RAM. A 1GB version of this card exists but
is very rare.
All three of these cards can be run in a PeeCee with OS/2 as its host
OS, or in an RS/6000 running AIX. Software installed on the host
implement channel controller emulation as a set of daemons, and DASD is
emulated using container files on the drives of the host system. The
container files used by Hercules are, not so coincidentally, identical
in format.
These cards are referred to as "P/390" and "P/390E", and one of them
installed in a PC running OS/2 is called a "P/390", but when the same
card is installed in an RS/6000, it is referred to as an "R/390".
I have a Microchannel R/390 system in an "unsupported" but functional
and rather nice configuration, in an RS/6000 model 397 running AIX v4.3.
The P/390 card runs either MVS (specifically OS/390 v2r10) or VM/ESA
v2r4, whatever I'm in the mood for. I also have a P/390E card, but
haven't gotten around to building a host system for it yet. The
(slower) Microchannel version is actually respectably quick, quite
usable. The P/390E is noticeably faster (I've used someone else's) so
I'd like to get mine running at some point.
If anyone comes across these cards and needs the software and
microcode to get them running, either for OS/2 or AIX, I have them. I
can also help with getting them running; I've done a lot with them.

So dnet-common and dnet-progs installed - but no support in the kernel.
So downloaded the nearest version of the kernel sources and am now 18 hours into compiling them.
Next step: How the HELL do you install a new kernel onto a Debian S/390 system? Man do I miss LILO.

SG1:: has returned. We have had several power failures today. The last
one took out the laptop "Console" on SG1::. That machine will be moving
to a UPS shortly.

I cah't reach various parts of HECnet right now, including area 1.
It appears from here that SG1 might be down or unreachable
but I don't think that accounts for all that seems to be wrong.

I just checked Amazon and they didn't have any z-series boxes for reasonable prices.
Also the power and cooling would kinda suck, methinks.

I think it sounds like lots of fun. It'd be even MORE fun if you're
able to do it on real hardware.

Go ahead. The Debian S/390 installer is almost a friendly penguin so you
should be okay.
The Debian S/390 port installation guide says
"Since Debian Squeeze, support for booting in ESA/390 mode was dropped.
Your machine needs to support for at least the z/Architecture, Architecture
Level Set 2."
I take this to mean that Debian no longer runs on a real S/390 machine but
requires a zSeries of some sort. Does that work with Hercules?
Yes, it does.
