This is the info that should be asked for permission to include within hardware related MAME source code files to ensure it doesn't get lost over time since web sites come and go. Granted it won't include visuals, but having text/info details is important.
I hope pcb owners use this to keep their Sega pcbs still working because there are still many alternate versions that have yet still not been found and dumped and preserved in MAME at this time.
