Very interesting. Hum yeah weird roms. What surprises me is the amount of diodes and resistors on there. JEDEC style roms do not need those. could they be micros?

EDIT2: Can't be JEDEC since A5+A6 would be tied, A3 would be floating.

EDIT1: And looks like bad hand soldered job, just like the other AY-3-85XX pong carts.
