 |
|
Hi,
Today I got bunch of CPUs including these two strange Pentiums :
First (on left) is Pentium 100 which have very deep engraved prints. Most of Pentiums which I saw had shallower or only with paint prints. It is for sale/trade 
Second one (on right) is Pentium 166 with unnormal printing :
A80502166
I716602Q
Q135 C 0238

Yep. chipcollector is right.
The Pentium 100 is probably a fake. I have a few fake Pentium processors with the same "unnatural" look.

It's a qualification sample, not and engineering sample. Intel was probably switching to newer stepping.

I think Morkork had pretty good explanation of different types of samples on his site. I'll try to find it.
