Some additional information on the prototype

Forgot to mention in my original post that the prototype also had a bigger plane on the playfield which dropped bombs (balls) during certian modes.

Have just installed a pinball pro sub woofer kit to mine, makes a massive difference, well worth the $'s

WOW.  The one in the vid sounded exactly the same as mine...But thats very cool.  One of the best playing D.E's..
