I have seen some of these before. I had some like this from TRW. Not sure of
the numbers though.
I remember the TRW was printed on a piece of aluminum which was glued on top
of a plastic chip. IIRC one I peeled apart had an AMD 2901 underneath. Most
did not have anything printed on the plastic underneath. Seems TRW was quite
propriatary.
I also had some that I thought were 68000s underneath but with absolutely no
markings.
We had to take the aluminum cap off before they could go into scrap. Never
saw one glued to silicon or ceramic.
2901s were at the heart of some early computers but is not worth the $175.00
that the seller is asking.
