David your the man! I've been desperatly asking around (amongnst my local
friends) for an Eliminator schematic so I could do just what you did!

Thanks!

BTW: I have a couple of Space Fury audio boards here, (there not mine). The
one labeled "Space Fury" has the installed AY-3-8912, and the one labeled
"Battle Star" does not. The owner claims the "Space Fury" board sounds
better. Fuller sounds. Do you (or anyone) know if Space Fury accesses the
AY-3-8912?
