I recall seeing a video on YouTube where this University hooked up hundreds of Mac G5s using nodes (I think) and chained them together in order to combine the processing power of all those Macs chained together. i also remember a small sidebar in an old MacAddict Magazine showing another school had done something similar using G4s. Now I have 2 G4 Digital Audio models with one being a Sonnet-upgraded 1.2 ghz machine, the other being a 733 mhz machine. Would I need a PCI card of some sort to achieve combining them together in order to form a faster machine? For those of you that laughed at my question I hope your coffee or hot chocolate shot out of your nose as you read it, haha. I appreciate all help and i hope that everyone has a safe and filling Thanksgiving. Eric Buczynski emax4.fortunecity.com -- Eric Buczynski emaxxx4 at warpmail.net
