It is possible I am misremembering, and possibly even smushing two memories of completely different systems together. We are talking ancient history and I only worked on these systems for a few months at most. On your die photos or block diagrams that you are referencing, are there references of where the graphics were hard-coded into the system? If I wanted to show the playfield, I could strobe an address that would draw the playield? If I wanted to show a score of 9 for player two, I could strobe another address? I recall that the playfield was frequently mirrored (left-right or top-bottom), so it was possible to combine bits of playfield for different games.
