hi i need steps on how to dissemble a pentium computer. i was wondering if anyone could give me a specific website because i looked in google but I don't know, I can't find what i want.

Question

It has to be pentium and it can't be pentium 2 or three or others.

Pentium is a processor, not a computer. Please read:

Your computer may well have an Pentium Processor inside, but it probably has a brand name on it somewhere. If not it may be a custom job.
