I was a little concerned about getting a counterfeit, but it is definitely a GI chip. It has the same number on the die as AY-3-8600, but the layer revisions are all L, whereas the revisions on the AY-3-8600 I decapped were all J.
I compared the dies and found 5 areas with changes. I created two GIMP XCFs with the 2 dies in layers, and a third layer with circles around the changed areas. I also uploaded jpgs because the XCFs are so large: www.seanriddle.com/gi
