I also have made a few mistakes with hardware like when i first started buying hardware to upgrade my amiga.I bought a ide bufferd interface and i cant remember why now but i had to strip my amiga down.So anyways to cut it short i plugged the ide cable in the wrong way and when i switched the amiga on i seen the cable burn infront of my eyes lol...It was like when you see them light a fuse in a cartoon as it was travelling up the cable heading towards my hard drive..Well yeah it toasted my bufferd interface lol oh well nevermind...
