All PIII 750's will be coppermines...no exceptions. The version that a processor is(ie. coppermine, katmai, tualatin) is mostly just looked upon by industry proffesionals or hardware enthusiasts. Intel really doesn't put this lable on the product. You have to take the product they give you, look at the codes, and then check the spec sheets to know what version you have. Or, in a situation like this, all PIII's(desktops only) between 650 MHZ and 1 GHZ are going to be coppermines. At the upper and lower ends of this range, there may be other versions(katmai on the lower end and tualatin on the high end if they ever release them).
