My Mame project is essentially done. Well… I can still do some cosmetic things, and I would like to find better Mame front-end software… but we have a working unit. Below is the finished product (click for bigger). This picture is looking inside, when I was nearly done.
So what you are looking at is a mini-itx MB, 1.6 GHz Intel Atom processor, a 125 Watt Pico-PSU, a regular 3.5 Hard Drive, an exhaust fan… all jammed inside of a Slikstik controller.
