Panasonic PT-53WX53G (55inch Rear projection TV) FREE
has a bad convergence IC, the kit to fix it is cheap - $60.
no HDMI but it has DVI so can be used as a monitor.
sound is amazing.
you can still use the tv as is, the red is distorted,
it's got wheels and it's heavy and FREE.
stick a raspberry pi with a wifi, bluetooth keyboard and mouz and you are in front of an arcade!
you're going to need a truck, and i'll help lift it in for you.
it's got a gigantic fresnel lens and a trapezoid mirror, and nice speakers for parts, if you just want those. the sound amp and video thingsmajigs are on two connected boards inside, so sadly i can't make it into a boombox, unless i was to use just the speakers - you might - i don't have the time to do it now - or the space.
My loss is your win FREE FREE FREE!
