This letter explains why we can't find manuals for these machines for online review.
Here is where you can get a manual according to the letter:

"...genuine documentation bearing

the Gottlieb Marks is available for purchase from Steve Young of The

Pinball Resource, 8 Commerce Street, Poughkeepsie, New York 12603

(telephone: 845-473-7114; fax: 845-473- 7116; email:

[email protected]). They are our official distributor of genuine

Gottlieb spare parts and documentation for North America. ..."

I would love to help but I can't find a manual - unless I buy one.
I'm hoping someone with more experience weighs in with better information.
