Since my last update, I've ordered and received the controller parts that I will be using for the controller. For this project I made it simple an ordered a 2-player starter pack from ArcadeWinkel based in the Netherlands. I don't have any experience with starter kits, or arcade parts for that matter, but the quality of the kit seemed nice enough for this first project :-)

The kit arrived in the first week of May, so I've had the parts lying around for a while now. Here's a nice picture of everything lined up on my kitchen table:

The kit contains (copied from the store page):

• 2x Balltop Arcade Fighter Joystick (top mount)
• 20x Concave classic push button (6x button layout + 2x pinball+ 4x service / menu / PC + 2x insert coin)
• Start player 1 push button
• Start player 2 push button
• iPac 2 player with USB cable (New 2015 version!)
• GND cable (.187 connectors)
• Microswitches

Now I just have to get around to building the actual enclosure, for which I've bought all the materials I'm going to need. I'm hoping to get the build done in the next few weeks, and then start with the electronics and software configuration.
