Well, let's see. I'm running on an AMD-K6 500 MHz, with Windows 98 SE and 375-ish megs of RAM. Background programs are a screensaver, a calendar program, a CPU cooler, and a personal firewall. I was multi-tasking when I started (but then again, I usually am ^_~), and I have no idea how long it went once I stopped the others. Anyway, the PZ3 just has freebies that won't do you any good without the objs and morphs of my own making, so I can send it to you if you want.
