I bought an AY-3-8610 from AliExpress to compare to AY-3-8600: https://seanriddledecap.blogspot.com/2018/05/gi-ay-3-8600-ball-and-paddle-games-ay-3.html

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
