Hi Sergio, Sequent was/is relatively stingy with information. They are now owned by IBM, who wouldn't even talk to me about my old machine. That said, the Symmetry series may be the closest thing to a real parallel computer that was ever done with Intel CPUs. They're very cool machines. I don't know the exact models you're seeing. Mine is a Symmetry S81, which accepts up to 30 386/16Mhz CPUs and accompanying Weitek co-processors. It is in a coke-machine sized cabinet, and impresses people even without the CPU cards ;) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); ' -----Original Message----- From: SP [mailto:spedraja@ono.com] It's possible I could obtain one Sequent Symmetry S2000-450 in a relatively short place. A similar system can be viewed in this eBay address: http://cgi.ebay.de/aw-cgi/eBayISAPI.dll?ViewItem&item=1311505028&ed… The system comes complete, with software, hardware and documentation. It need three pallets to be transported. There is another opportunity to get one Sequent Symmetry S5000 that uses 4 Pentium processors and 1 Gb of memory, but this is in private negotiation. Do Somebody has information about these systems ? They appears to use Four processors 486, a Numa architecture to share memory, and one version of Unix named Dynix. Is there some porting of the Gnu utilities to it ?
