My collection consists of:

Mario Bros. -- Dedicated cabinet. There seems to be some issues with the sound. Could use a cap kit.

Ninja Gaiden -- In a Wizard of Wor cabinet. Was also a Galaga at one time judging by the burn-in on the old monitor tube. The sides have been stripped and painted black. Needs a cap kit.

Tank -- Cocktail version. Needs a lock on the coin mech and a tube swap.
