Punch-Out!!

Nintendo, 1984

Punch-Out!! is a classic boxing game from Nintendo, and like most Nintendo titles, has terrific characters. Your first (and easiest) match is against the Frenchman, Glass Joe. As you progress higher, your opponents become more difficult, ending with Mr. Sandman from Philadelphia. The secret of the game is learning the individual behavior, weaknesses, and "tells" for each opponent.

Punch-Out!!'s most unique feature is the use of dual monitors, stacked one on top of the other. In addition to the regular buttons and joystick, the control panel also has a large industrial-style mushroom button, which is used only for knockout blows.

This machine needed one monitor recapped, the power supply un-hacked and repaired, some work on the marquee light, and refurbishing of the coin door.
