| The are two versions from Atari and one version from Namco. The two pictures here are the Atari Versions. Each board has a distinctive layout. When looking on http://arcarc.xmission.com/ for the RAM and ROM failures you'll need to figure out which PCB you have and match it either to Type "A" or Type "B". This will give you the physical location of the RAM/ROM chip that is reported as bad. For example, a bad RAM of 3L is physically located at 9H/J on a Type "A" board and 7L on a Type "B" board. | | CPU | ieure |
