WAR STORY: I was the technology coordinator for a school district back in the mid 90s, and we had a very locked down network to prevent the lil' darlings from getting to babes4u.com. Well, I had an inventive teacher that wanted to use her Compuserve account while at school to go places our network had blocked.
I got a frantic call to come to her classroom immediately, big computer problem..
Walking into the classroom, I can smell the electronic "burn" and ozone smell permeating the classroom. I asked the teacher what had happened, and got those innocent, "Gee I don't know, it just stopped working.." excuse.
I look in the back of the machine, and the CAT5 network wire was removed, and there was a... uhhh.. "adapter?" plugged into the RJ45 on the back of the computer.
I followed the wire, and noticed that about six feet later, the CAT5 cable was cut, and there was another cable attached to it.. OK... I followed the cable along, and at the end of the "added" piece of cable was an RJ12 (phone line) connector, and that connector was plugged into a phone jack on the wall behind the computer.
Before I had a chance to ask, the teacher blurted out, "I just wanted to dial into my Compuserve account.."
So she had evidently looked at the back of the computer, saw the RJ45 network jack, and since she couldn't plug her phoneline cable in there, she made up a cable of her own. Figuring, of course, that by plugging into the phone line, and then into her computer, she would be able to use her dialup account.
I was agog, simply agog. (Apologies to Eulalie MacKechie Shinn)
EPILOGUE:
What happened, of course, to fry the system, was the "hybrid" cable the teacher had made, where she carefully spliced the little wires from the phone-line into the CAT5, being VERY careful, of COURSE, to match the colors. And the result was that the phone company's 48VDC fed right into her computer, and when I looked into the machine, it had literally made several of the mobo and GPU chips GLOW until they finally burned out.
Ahh, technology! Ain't it wunnerful?
Cheers!
