Quoted from Ockeyhead:what is the actual weight of all Sterns, Gottlieb system 80's, Spooky, all Bally/Williams including system 11's, Sega's, Capcom & EM's, etc.
It depends on the title and era. Early solid state are fairly light.
Alphanumeric & DMD games are usually 300+
Modern games vary, depending on how packed they are. Last I heard, woz was the heaviest, although POTC looks pretty packed too.
