The Williams Defender cabinet shared the "base cabinet" with many other games like Joust and Sinistar. This fact makes it very easy to make multiple control decks. The control decks dimensions are 23 1/2 inches by 8 inches made of 3/4 plywood.

We have a few leftover parts from the last MAME project, also a set ordered [http://www.ebay.com/itm/360450175737] form Ebay seller TwistedQuarter for $29.99 plus $10 shipping as a donation.

== Custom Electronics for the Controls ==
A custom board was fabricated for controlling the buttons and joysticks [http://vusb.wikidot.com/project:mamepanel V-USB MAMEPanel] was ported to work for the Atmel atmega644p micro controller. The hardware currently emulates 2 joysticks with 8 buttons each and a keyboard hid device. MAMEPanel is expandable to 3 joysticks and a mouse input is also possible. Below is the current keymap:

The Williams Defender cabinet shared the "base cabinet" with many other games like Joust and Sinistar. This fact makes it very easy to make multiple control decks. The control decks dimensions are 23 1/2 inches by 8 inches made of 3/4 particle board.

We have a few leftover parts from the last MAME project, also a set ordered [1] form Ebay seller TwistedQuarter for $29.99 plus $10 shipping as a donation.

Danny is currently running a custom firmware on an Arduino Uno and checking the results of that.
