Today I finished my latest wall mounted arcade project (Q*bert) which will probably be the last for a while as I am now out of wall space. All of the machines plug into a recessed outlet behind the machine so the cord doesn't show (except for a little bit of the Tempest cord which I realized after seeing the picture I need to tuck back in). All have a button that looks like a coin acceptor but they do not take coins. All use LCD monitors (a CRT would not fit without making the cabinet a lot thicker and heaver). I like this cabinet design as it allows the feel of the original while using only about 1/4 the space.
Robotron: The first one I made. Powered by a Raspberry pi.
Rampage: My second machine. The only one in which the CPO and bezel do not match the original. Powered by Raspberry pi.
Stargate: As plays defender. Powered by a raspberry pi.
Fix-it-Felix Jr: Also plays many other games that can be played with a single joystick and 2 buttons. Powered by a Windows 7 PC.
Tempest: Set up to be switchable between several versions including Tempest Tubes, As plays Major Havoc, Star Tac, Arkanoid, and Bomb Bee. It has the spinner dial and volcano buttons from an original machine. Powered by Raspberry Pi
Q*Bert: Has a 4-way joystick mounted diagonally. Has a knocker similar to the original which fires when Q*Bert or Coily fall off the pyramid. Set up to play several version of Q*bert (Mello Yello, Qubes, etc.), Tylz, and Congo Bongo. Also Raspberry Pi.
