Sega Arcade System 16 Altered Beast and Shinobi boards

[vulcanjedi]

Greetings Programs.

I have two Sega arcade boards. Altered Beast and Shinobi. I got them from a reliable source that said the AB was working but the Shinobi wasn't. Any idea what a System 16 board goes for or is worth? Or if the roms are worth anything?

Thanks

Mark
