IC chip identification

[zeno]

What is this IC in ? That may give clues. It was common to scrub parts
by some MFG's. Keeps then in control of repairs etc.

Some newer IC's have programable micros like the common Toshiba TMP###.
there is a 3 to 4 digit ## at the end that gives the part ##. Dont matter,
no way to program the "blank" IC without deep knowledge.
