Intel 80286: Customer Sample or not?

[gshv]

I bought Intel R80286-10 processor with stamped "CS" on the back:



I have Intel R80286 processors with "CS" and other two-letter codes on the back. Their two letter codes are always the same font and size as other markings on the chip. So, do you think it's a customer sample or not?

I think I am going to have to say no on this one.

Just as Pentiums that say ES on them arent samples.

I think ES is the same as CS? But CS is not used any longer!? I've only ES 286 seen. I traded mine with Karolo

CS = Customer Sample = Items given for free to a customer who plan to buy thousands. Strictly indentical than the commercial one from a technical point of view.

QS = Qualification Sample = The same as CS, but used later.

ES = Engineering Sample = These CPUs are the only engineering sample, i.e intended for debugging purpose only. They are in an early stage of development and not exactly the same than the commercial one from a tech point of view (like a Beta software, they are Beta Hardware).

Currently, Intel processes for a new processor use three generation of engineering sample (A0, A1, A2) and one generation of Qualification Sample before launching.

I have informations to recognize QS from ES, and the different level of ES. I'll publish them soon

hi genna,

i own 16 LCC Intel R80186-10.

5 have thin CS like your left one,
3 have thick CS like your right one,
4 have CT (3 thin, 1 thick),
4 are different

so i also think so, it's not a customer sample (if yes, i would be happy

best regards, borris

hmm, i can't find the thick "CT" any more but i found 2 others with "BY" and "CC". BY is older than CC is older than CS.



i think, i'll throw "BY" and "CC" away

btw: if someone wants to buy ulta-rare R80286-12 Customer Samples ("CS"-marked), please contact me
