hey
i have a galaga that when it boots up all i get are
00000000000000000000

across the entire screen

cleaned all custom chips and replaced all custom chip sockets
all voltages are good
anything else
 
Most likely something wrong with the either (or all) of the custom chips at 2E, 2H, 2J, or 2L...
