My Pacman has been displaying garbage whenever I turn it on. When I turn it on, I usually get nothing, or sometimes I get a single 0 on the screen. Then, if I turn it off and on again, I get garbage on the screen. There is no sounds, and none of the switches are doing anything. The reset button also does nothing. I have reseated the edge connector, and socketed chips. All voltages are correct. Any help would be appreciated.
Thanks in advance.

Thanks for the replies.
I have verified all the rom's checksums, and they match up with the ones in mame. It looks like I'm going to have to order a Z80 and some 2114's, as I don't have any laying around.
