Mike Ross, (remember him?) has one and it is the size and weight of a good sized person. 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. ;) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
