Re: Asteroids Help

Y'know, I just noticed that the 3 asteroids boards I have are laid out differently
than the schematics show. Which is probably why I'm also seeing different
signatures than the document. These boards are all marked with the serial number
A034986 -05. Since the address bus is different - are there specific roms or
anything about this board that I should know about?
