mitch074 :
OS'es worth running on it:
- Linux or BSD, with a stripped down desktop envioronment (Xfce or windowmaker; GNOME or KDE won't run with so little RAM)
- Windows 95/98 (Me chokes on 32 Mb)
- Window 2000 (completely stripped down, it barely, but does, run)
The CPU is beefy enough, but a 650 MHz with only 32 Mb sounds strange. Plug in a 256 Mb SDRAM stick and it'll do well with any of those OSes. Enough for a server, or a Web browser, or a desktop unit.
A Pentium 3 600 EB with 256 megs will run XP, with 384 megs it will do so beautifully. A P3-650 is not limited to W2K and will run it more than just "barely." Remember that the Pentium 3-600 came OUT in 1998/1999, and is hardware current with windows 2000, and XP is now an "old" operating system that was developed on a P3 platform or earlier. Vista would even run but would not be at all nice on less than 1 gigabyte, which most P3s wouldn't support, so THAT is the OS which would present a P3 with problems.
Here's a pared-down CPU-Z grab from my P3..
