AMI manufacture I believe Pulled from OLD Digital Test Meter CPU Gold and White and Gray trace circuit lines, Lids are epoxied on, Mid 1970's NO extra data on them..  This is what a Ebay friend adviser told me:

For starters, I believe there are two date codes on these chips.
Top one is 13th week of 1977.
Bottom one is 11th week of 1975.

They are both "grey trace" chips -- and their manufacturer's logo is hard to read, but I know it says AMI.

It is an earlier version that the screen shot below (which shows more-recent logos), but I have another screen shot that I will attach that verifies the identification as AMI.
