I had a 1950's articulated brass desk lamp on top of a PC tower, with a bookcase at the end of the desk, on which sat an IBM badged HP pen plotter.
While hooking up the serial cable it slipped out of my fingers and touched the lamp base and the port on the plotter simultaneously. KAPOW! 120 volts through the shielding of the serial cable into the grounds of both the PC and the plotter. Didn't do any damage except for burning a nick in the edge of the cable connector. Could touch that lamp and not get a shock, didn't pop the circuit breaker either. I unplugged it, sometime later pulled the cord out and found a cut in the insulation where it went through one of the hinge joints in the arm. Cut about 6" off the cord, made sure all the spots the cord passed through were deburred and rounded off, reassembled it, gave it to my sister. ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite It's a free troubleshooting tool designed for production Get down to code-level detail for bottlenecks, with <2% overhead.
