Need manual for Darius stand up 3 monitor arcade cab

[Enmity]

As the title says I need the manual for this cab or any information someone might have like if there is a debug/settings menu and how to access it. I just recently picked one up in fairly good condition, but I need some specific information about what button switches it originally used since I'm assuming the previous owner replaced them at some point. As well as any kind of changeable settings and such.

I just found this forum while looking for information on this can and it seems like a great place to find information for these games.

Thanks for any help.
