Hi all,
I have seen several plastic DIP IC's from the 1970's have a white ink stamp
on them that
say something like "ETC 4" on them. (Your number may vary) Most are Intel
RAM's, but some are Signetics or National TTL. Before I have seen them on
chips on boards, but have now bought a bunch of IC's new in tubes which also
have this stamp.
Has anyone else seen this and know what it means?
