Yes, like Sonic; S1 to 39K resistor to anode of diode, R to 120K resistor to anode of another diode, both diodes' cathodes to base of transistor.

It actually looks like N81. This die doesn't have the 2nd die ID, just the one under the top metal text KMS 73B: www.seanriddle.com/batmantasid.jpg

Since I dumped this one electronically from a 2nd game, I haven't removed the top metal layer yet.

Yeah, N81 makes more sense. The game is between Sonic(N71) and Sonic 2(N86).
Did you scan the background inlay?

I had a Batman TAS and was sent one, so I scanned both backgrounds: batmantasbkg.tif and batmantasbkg2.tif

I've only looked closely at 3 of the "girl" style games that are in the larger, more colorful cases, but the PCBs are all very similar. In contrast, there were very few PCBs in the other style that were similar.

Who knows why, maybe the model 72-xxx series ("girl" games) were done by a different team.

Here's tbatmana in MAME:

I added a die shot of the AY-3-8605 and pics of all 3 with the top metal removed. http://seanriddledecap.blogspot.com/

A fellow commented that he reverse engineering the AY-3-8500: https://plus.google.com/103546033861220813867
