Bonjour François et Thierry!
Are you looking for an "official" test PROM made by Gottlieb?? Did that one ever exist?
Curious about your results. I never studied these boards in order to make a test ROM. The integrated ROM area in the 6530 chip is a challenge I think....it would take a different approach to write a test ROM for these 
Keep us informed! It would be nice to have a decent tools to repair these boards 
Good luck & regards from another test ROM writer from Holland
