I have these gold chips that came to us from someone who was very sad to part with these. I need some kind of knowledge on the value and/or history of these chips.
I haven't seen anything like them before and I cant find any info on them. The packages they came in has the address to the NASA Ames research center. We think they might be military grade CPUs.
Here is an album of the gold chips: imgur(dot)com/a/ICYQZ
Thank you
not sure if I would call the chips rare....but having that many might be rare.
