I'm looking for the following chips:

Any Engineering Samples (Indicated with the words "CONFIDENTIAL", S-Specs that begin with Q, rather than S. )

Intel C4040, C4004, C8086, C8080, MC8080 (Any variation of any of these in the C Package, and I'm interested.) 

I'm also interested in doubles or spares of my own chips. Don't hesitate to email me.
