Thanks Spark!
I did have an idea of how i could fix the retainers. I probably would have just removed some material from the top of the cab so that the mounted retainer bracket was flush with the top of the cab. I was kind of into adding more t-molding tho.
So, this thing is basically done. I'm sure I'll make upgrades over time, but I'm really happy with it as is. I realized after some fooling around that the double throw switch thing was not going to work out. Then I remembered that there's a special section in the OS X key commands preferences that allows you to re-map any key command, for any application, so long as you follow the general guidelines (One of the buttons has to be command, option, or control, and one has to be a symbol/character). After determining, which symbol and command keys were already in use by the iPac, I was able to come up with an 2 button sequence that is unlikely to occur during play. The sequence is L Control (Button 1) and 1 (Player Start 1). This allows operation of the machine without ever having to touch the keyboard for most functions. I've been playing it this way for days, and not having to open the drawer really makes it feel more like a standalone machine. I also added a switch hidden under drawer opening, that can turn the marquee off and on. This means I can basically just leave it on all the time. The computer/display just go to sleep after a while. It's nice to be able to go down to the basement, click a button to wake it up, and be in game in a couple seconds.
I'm having so much fun with this thing now, It's great. Whenever I have a couple minutes, I'm down there trying to beat my last high score.

By the way, anyone know how to get it to keep high scores in MacMAME? Once you exit a game the score info is lost.
Here are some pics of the unit complete... sorry for the quality, I'll get some better pics/video, when I have a little inauguration party for it.



Installed hinges for easy servicing. Still need to put the brackets in to seal it up, but I'm having too much fun playing it. I'll just be sure to get then in before I move it anywhere.


This is one of my favorite parts of this build. It doesn't look like much, but that's not what's important. I was totally freaked out about cracking open my laptop to put a boot switch in, and even more freaked out about wiring up my poer entry module. But it all went very well, and works great. I really love the sound system too. It sounds great, and really kicks for something so small. Can't beat it for $5! It's nice all cranked up when playing Guwange, or DoDonPachi!
The other day I built a simple table for it to sit on in the basement. I'd got just enough room on each side for a beer. So far it's seeing quite a bit of action!
