Original, non-working American Technos Block Out arcade game circuit board from 1989. This board boots up and is playable, but is missing the background music. The other sounds appear to be working. We have done no troubleshooting. We did notice a couple lighter scratches on the back, so it may just be a broken trace or something more.
Boardset is sold as-is for repair or parts. It is fairly clean, see photos for more details.
