Hello to all..
I have 3 group pictures that I would love some help with to identify which category to put them in.

Group 1 (2 cpus)- left pic is a pinless w/ gold cap (Is this still
considered pinless?)
right pic Siemens (looks to be possible
386/486 group?)

Group 2 ( both AMD386 - green fiber w/ metal is my guess) The question is 3rd pic in this group that shows how one is different with black ceramic or plastic plus how the gold pins go thru that black layer and has more gold.

Group 3 is a large ceramic w/gold cap with the four little boxes on ceramic side seem to be goldish color on the ends- Would this be considered Foreign?
