Just one OLD non-evolved P-II 400Mhz w/ 8Gb HD which I've been using ever since I first got Bryce 3 and Poser 2. The only upgrades I've been able to afford for it was bumping the memory up to 256Mb and adding a 40Gb external HD. Hoping that MAYBE by the end of next year I can afford to get rid of it and move to a 'new-er' obsolete machine. DREAMING that maybe someday I can afford to have a machine that's not already several 'generations' (of PC's) into obsolescence at the time I buy it. I have certainly learned the truth in the computerland axiom "If you can afford it, it's obsolete."
