When I first got this Asteroids machine it had been pretty well gutted. There were no controls, no monitor etc. I wanted my HotRod to work into the cabinet somehow but wasn't really sure how it would work out. The Hotrod never controlled the machine as well as I wanted so I really felt the need to have a keyboard added. Since there was a huge gap under the Hotrod I decided this would be a great place to have a drawer that would slide out from under the Hotrod & contain a keyboard/mouse combo. I then had the idea of trying to add every controller a person may need to play any of the MAME games... I.E. a Flight-stick, trackball, light-gun, steering wheel etc. I never did get around to adding the steering wheel but did try other solutions with the flight stick, which I ended up fabricating a mount that would go over the HotRod & be adjustable to hold a flight stick, trackball, or whatever control you would want. When it is removed you can't tell there is anything there under the HotRod. The Light-guns I thought would be cool to have slots to slide the guns into but then saw another idea of mounting holsters on the sides of the cab. I went with some guitar hangers which I painted to match the theme of the Asteroids sides & used those as the light-gun hangers. I wanted the quarter lights to function but not to just light up - so I switched the bulbs out for lower capacity LED lights and ran them to the Motherboard. So, the left Quarter light depicts the power light of the computer while the right quarter light shows the Hard Drive activity. The old "Test" switch inside the quarter door I wanted to integrate as well, so it actually functions as the "On/Off/Reset" for the motherboard. I went through several front bezels in an attempt to get one that would work with the light guns (sensor bars) & would be sturdy enough not to crack or break with the movement of the cab. What I ended up with was a 1/8 inch thick plexiglass I painted leaving very small openings in the paint for the sensor bars to pass through. As far as the sound goes - there were no speakers in the cab when I got it, I installed computer speakers in the top of the cab while I converted the marquee light to run off of DC power & attached it to the PC power supply. There was never a back on the machine so I did put a simple door type back on the machine for easier access to the machines' guts. Anyway, I wanted to share the project with the forum & get some feedback and or ideas about the project.
