Awesome pictures. It's seriously impressive how these chips must be made and
designed.

I'm talking about his asking price. I bought one three years ago from a
fellow collector of CPU chips for _$20_ that had some markings worn off and was
scratched. I opened it up to photograph the die (a hobby of mine):

I've haven't even seen rare versions of white ceramic 4004 ICs in
perfect condition go for anything close to his asking price. I've seen a
complete, mint condition MCS-4 (4004) chip _SET_ go for something close to $1K.
