Description

Wire Speakers

The speakers are wired with 16 gauge speaker cable.  The speaker wire runs to an amplifier that I removed from a pair of PC speakers and mounted inside the cabinet near the computer.

Install Speaker Grilles

The speaker grilles are installed by attaching four screws through the grille and the speaker behind the panel and securing with nuts.  The face of the screw is painted black with a can of black spray paint to better blend with the grille.

Insert Coin Door

The coin door is slid through the cutout in the front door and attached with the mounting hardware that comes with the coin door.

Wire Coin Door

The coin door quarter mechanisms are wired to the keyboard encoder by grounding one lead on each switch and running a wire from the other lead on each switch to the terminal block inside the control box.

The lights behind the coin reject buttons are wired to ground and 12V.  Light bulbs do not have polarity so it does not matter which leads are wired so long as one is attached to 12V and the other to ground.  The 12V supply comes from the power terminal block inside the control box and is provided by the PC power supply.  All the wiring is secured inside a spiral cable wrap and attached to the side panels with wire ties and mounts.

Attach Control Box Brackets

The control box is attached to the cabinet with six steel L-brackets.  The L-brackets are screwed to the 2x4 frame with the supplied screws.  Sticky foam is used to cushion the control box and to absorb irregularities in the wood to provide a more solid surface for the control box.  The control box is positioned and holes are drilled through for each of the holes in the L-bracket.  Twelve 1/2" x 2" bolts are used to fasten the L-brackets to the control box.  Each bolt uses two washers, one lock-washer, and one hex nut.

Install Monitor Bezel and Lexan

Eight holes are drilled through the Lexan and bezel to accommodate eight black finish screws.  The bezel and Lexan are positioned against the 1x2 rectangle previously built into the frame and screwed into place

Attach Control Box to Cabinet

The control box is attached to the arcade with 12 1/4" x 1 1/2" bolts with washers, lock washers and nuts.  The cover between the control panel and the monitor Lexan is a piece of painted sheet metal that is screwed to the bottom of the control panel.  The edges of the sheet metal are bent in so that they are not sharp.

Insert and Cable Computer

The computer is slid into  the lower cavity of the arcade.  The monitor, PS/2 mouse cable, sound card output, and keyboard cable are attached to the back of the computer.  A drive power connector is attached to the relay in the power strip used for the one step power-on feature.  A second drive power cable is wired to a four position terminal strip in the control box to provide 12V, 5V, and ground for the control box and coin door.
