Wow... I think very rare liao. Pentium4 maybe can find. You sure your mobo can support Tualatin cpu?

One of my cnc machine that has broken down actually has a working cpu inside... very epic cyrix 233MHz iirc, 16mb edo ram (I added 32mb later on but took it out after it started to crash quite often iirc). Its a PITA to find a working IDE hard drive that would work with it though.
