I just went through a box of 90's PC parts, and found this among the 10BASE-T AUI thingies and 30 pin RAM, any ideas as to what it is? Google searches of the text on the die cover yield nothing.

Here's the photos.

Maybe you'll have more luck (unless someone here knows)

As for AMI - they are apparently now called ON Semiconductor.
