Help with PGM scrambled graphics

[Arcade-Projects]

My PGM showed up and I bought Espgaluda, Dodonpachi Dai-Ou-Jou, and Ketsui Kizuna for it (from china).

I cannot get it to play anything.

The package showed up loose with the feet broken off and the DIP switches on the side are all in the OFF position.

There is an empty Expansion connector

I am running the board at +5.03 volts.

Is it broken or am I missing some basics of operation?
