This is something that has eluded me for a very long time. I'm new to this forum, so thanks for entertaining these thoughts!
Up until today, I didn't even have a photo of the outside of these machines. Found a great article on CPUshack that showcased this view, and specs of such a beast: http://www.cpushack.com/wp-content/uploads/20 … 028_xr6_big.jpg (full article here: http://www.cpushack.com/2019/01/12/mini-mainf … rver-from-1997/ )
I own an Aquanta HS/6 which has been discussed on this forum before. It's a beauty and a beast. I know that Pentium Pro CPUs were designed for a maximum of 4-way connections without any hardware "glue", and I believe the Aquanta HS/6 (aka ALR 6x6) used something like this to get to six CPUs. Simple to imagine that the fourth processor in a cluster wasn't actually a CPU but a relay to another cluster, where every CPU logically sees four, but one of the four is actually another three. I cannot understand how this would scale farther and still be compatible with standard operating systems like Windows NT 4.0. The ASCI Red supercomputer was built using these chips, breaking the teraflop barrier, but supercomputers always beat to their own drum.
So, I'm just immensely curious: does anyone have any experience with an Aquanta XR/6, even seen one, or know of any resource for photos of the inside of such a beast? It's a dream to one day own one, if any have been saved from the scrap heap. At the very least, this is such an interesting hardware story that has never been told and I'd love to know more.
