The very first time I kill screened on DK was a cocktail machine. I pulled it out of the trash at a local vendor and brought it home. It needed some repair but was complete. This was before the home PC boom, widespread internet and before there was any kind of market or collector value.
I remember a Tempest cocktail sitting outside in the trash as well as some other upright games (most missing some parts or not working)
Yes the way the stick is oriented to the cabinet is very awkward.
