I had some time this weekend and my daughter and I decided to put to use some joysticks and buttons I had bought a few years ago. I bought an IPAC2 from Ultimarc (3 days from the UK, what what) and a 4x4 piece of 1/2" MDF from Home Depot. We used a 1 1/8" Hole Saw to cut / mangle the holes for the buttons and joysticks. Since this was to be a test of putting it all together we were careful but not overly concerned if things didn't come out perfect. At the end of the day we realized the button placement was spaced a little too far apart but that can be fixed in the next revision. We spent the next day wiring up the panel and IPAC together and downloaded MAME. Out of the box, everything worked as planned and we enjoyed some gaming for the rest of the day. Overall pleased with the results and we are designing our next control panel now.
