Arcade10 Build Day15
During the week I repaired an old Dell XPS T500 - (replaced the CPU fan from an old server, clocked it back to silent with a 33ohm resistor)
Run up MAME .128 (I have newer versions of the ROMs but this version has save state support for my favourite game Galaga)
Applied my little box of tweaks to hide XP, (I did not go all the way because the machine has a trackball, I can lock it down further later if i want)
Major work was building a switch box to power up all the 240v devices after the computer turns on. 12 volts from the computer trips a relay which switches power to a power board. (I know you can buy these things but, I have never seen one in a shop and I wanted to make my own) All I had to buy was a 20A relay and a jiffy box.

I also wired up the coin button and coin mechanism switches (in parallel)
12volts to the coin button light
A cable to the back of the PC's ON button so I can mount it remotely
An AUX input cable to the control panel for the coin buttons (I have a few spare wires in the CAT5 cable for other inputs later if necessary)
I wrapped the two USB cables from the control panel and the AUX cable in a plastic cable wrap. <cheat> now I have my one cable to the Control Panel, </cheat>
All these cables I put in, I used plugs on the ends so that everything is quick disconnect to aid working on it or a quick control panel or PC swap out.
Coin switches and light wired up with quick a disconnect plug

Used a 3.5mm audio plug here as I only needed two wires for the coin buttons, I can replace the plug later with a din type if I need more switches.

Here you can see my single cable bundle coming down from the control panel.
A picture of the coin button lit up.
Here it is with the all the bits and pieces together.
The plan is to replace the PC speakers with something more decent. I recon a car stereo (one of the ones with AUX and USB inputs and MP3 playback) Also have to mount my light for the marquee and a power button on the front and …. Ah there’s my list starting again.
