Hi all,
I've got a dead track and field board here. However, it seems at some point Konami ditched the whole Konami-1 and custom chip thing and went with a vanilla 6809 based board.
Are there any schematic or ROM images out there that I can check this board with? I got the CPU to quit watchdogging, but all I get is some color on the bottom of the screen which goes away about an inch at a time.
