I can`t find any info on this chip but it looks a lot like the AMI S6800 below.
It has 6802 marked on it with a sticker.

Nice Chip!

I think someone has a system to test/identify it.

Are the legs gold?


There is a bluish-purple discolouring on the top of the legs but the bottoms are gold.
It`s a bad view of the chips legs in the picture.

The chip is nice, but I have no idea if it's a 6802 or not. BTW, I have 6802 in the same package, only with tin pins:

I tried some silver cleaner on the legs and was able to remove some of the discolouration. It looks as though the legs are tin or silver when I looked at them after in better light.

You could test some pins with a multimeter at diode-test position
and compare the results with an also tested 6802.
