Currently stumped on this Burger Time I'm working on. Graphics are as-seen in the pics. Did some reading on the forums but nothing specific to what I'm seeing. The only thing I read was from a post mentioning grounding the outputs of the LS194s after the graphics ROMs. Doing that doesn't move the misplaced parts of the graphics that are being seen on the screen. Swapping the bottom board(the one with the CPU-7) fixes the issue, so it's related to this board in the stack. Also swapped the 6 graphics EPROMs as well. Looking at the screen, it appears the misplaced parts are OK on the vertical, but not on the horizontal. Used the SLICE comparator on most of the chips on this board and all nothing flagged as faulty. What am I missing here???
As always, thanks in advance for any advice!!
