Power-Jack Turn a computer on / off independently! This is about as simple as it gets in the computer world: Plug our cable into your PC's ATX motherboard, screw the tab in place and plug in your favorite switch! You are now able to turn your computer on and off, or even reboot it when it locks up! No software to load, no hardware conflicts! The jack uses a standard 1/8" mono (audio) jack to accept any industry standard switch: From a simple button switch, to something you drive your chair into to press, plug it in and turn your computer on! This will work with any newer PC using an ATX motherboard, (used with P-II or better CPU's.) Minomech Enterprises http://www.minomech.com/Prod_ME_PJ.html
