Thank's
Hello,
Not yet found the test prom ...
But found why the 7643 sound rom 664 Pink Panther fails when using an adapter for replacing 6530 with 6532 and eprom.
More info on our web site soon !
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

Bonjour Marco,
Yes we are looking for official sound prom. We think they have existed by studying the 6530 code, when activing the 'spare' input ...
