Hi!
I'm having a few issues with one of my Pacman boards that have me a little stumped. I've done some searching but haven't found anything that seems to be close to my issue, but I'm not the greatest at searching forums, so I apologize if this has been asked before.
I have garbled sprites like this image in attractive mode

Once I coin up and press start, the screen looks like this:

Occasionally the maze will disappear and all the characters can move freely around the screen. It also has sound.
I can boot the test ROM in 6E, but I can't read anything because of the distorted letters.

There's also a capacitor that someone added between pin 11 of the LS377 at 4B (the clock pin tied to 6MHz) and pin 7 of 4C. When I disconnected that, it would show the test patterns and then reset at the beginning of the attract screen.

I've replaced all the sockets, RAMS, and all ROMs are freshly burned and verified. I'm also using reproduction sync bus controller and VRAM addresser boards from Mikes Arcade.

Thanks for any help!
