I wonder if it is same scenario like Kee Games Quiz Show manual print. Maybe not, but as I recall the Quiz Show manual also left out a fair amount of details including the cpu type (S 2650 cpu) I don't know if that was intentional in order to throw off rival companies or make it harder for repairs to be made by non affiliated repair firms.

Andrew provided the exact correct answers.

With some proms, especially any proms that contain graphic data image contents, it is possible to view the images themselves using Marc Lafontaine's program called Ripper.

The downloadable program file can be found in this old post.

Marc Lafontaine

For those that have seen data images for Bazooka and wonder how they were generated, it would likely be from Marc Lafontaine's program called Ripper which can be grabbed from here as a zip file attachment. The zip file also includes same instructions I typed here for how to view PSE game images and an image of airplane targets from Desert Patrol.

As an example, Matt showed that the prom that stores parachute images from his own Desert Patrol pcb was in readable condition.

There is a bit of a learning curve with Ripper, but it does work with 1970s era arcade game pcbs.
