Here is my Millipede Cabinet that I recently picked up off ebay. It's a wreck. I believe it used to be an Arabian that was converted to a Millipede. I'll give you the pros and cons of the cabinet.
Cons: Most of the exterior MDF is unsalvagable along with the artwork, Monitor has major screen burn, I believe I'm missing part of the wiring harness.
Pros: Trackball works, coin door is in good shape and almost all intact, marquee and bezel are both glass
Work done so far: trackball pulled, cleaned, and rebuilt. power supply rebuilt.
Currently I cannot get any signs of life out of the cabinet because I believe I am missing part of the wiring harness. It seems I'm missing a piece that goes from the Audio Regulator Board up to the monitor on the right side of the cabinet. I'll post pics below. If anyone has any information on this I would greatly appreciate it. The Millipede conversion kit could be put into a Dig Dug, Arabian, or Kangaroo so if any body has one of those cabs and can shoot some pics of the inside of the cabinet that would be great.
