Shut down windows vs just powering off PC

<< < (4/9) > >>

Beretta:
if you want to wire up a button to a standard ATX motherboard it's simple.. just run the 2 wires to a momentary contact button.. a arcade button will even work..

one side to "COM" the other to "NO", does'nt matter which..

you just need to make a momentary circuit to power on the board.

This is the point where I diverge from the illusion of having an authentic arcade machine.  My cab powers down just like a regular pc, with a windows desktop and all. 

This sort of detail has absolutely nothing to do with functionality or gameplay, and doesn't look bad at all. In fact I kind of like the seeing that desktop for a brief second during startup and and shutdown, reminds me that it's a MAME cab after all. 

BUT, if you must I suppose you could always rig your monitor power and speakers to one switch and the pc power down button to a tiny button next to the switch.  This way you can flip the monitor switch to get that nice bump sound from the speakers and see the crt shrink like an old tv.  Then you can push the power button (I recommend a led lit one) to turn off the pc. 

OR, you could just run your cab off of a CD and have it store everything in RAM.  In this way you can turn it on and off just like a real cab.

here is what i did:


1. get a free pushbutton
2. get some wires
3. rip a power switch from some old pc housing
4. extend the cables from the power switch to your pushbutton
5. wire it up to the microswitch

and voila it works !  i have a vid up on youtube showing it

Just cutting power to a computer happens in life and is normally not a threat.  However if you are doing it on a regular basis, that's something different entirely.  Just cutting power can cause power surges that will damage the computer.

True story;  My cat once stepped on the switch under the power bar of my desk.  I crawled under to reset it and turn on my computer and it wouldn't POST.  Turned out that she managed to burn out the RAM by cutting power with the power bar.  The POST diagnostic LEDs were reporting failure at memory check and the stick had to be replaced.

Now, this is a remarkably rare occasion, I imagine I could hit the power bar under my desk or blow a fuse or something and the computer will be fine.  Do it OFTEN enough however and eventually it'll bit you in the ass.

I got a couple momentary buttons from radiocrack that I'm going to install behind the coin return doors. They're the 3amp kind, 1 red 1 black, and they're very low profile, they don't stick out far at all which I love. Problem is that they need a 1/2" hole to put them through, and half inch bits are massive, so I have to figure out how to drill through the steel of the coin returns rear, but I have tons of tutorials and info on what bits to use and stepping and all that. What I don't know however is what gauge wire to use to attatch them to the mobo switch wires. I was thinking of tearing open an ethernet cable and using a couple of those but I'm not sure if they can handle it. Any ideas for me? Also, what gauge wire does the cp buttons on the arcade use? I need a few to attatch to a t-tap wire splice on my harness for the J-Pac.
