i have a few motherboards lying around and decided to do up one of them
while playing around with a socket 7 mobo, fitted an AMD K6-2-400 that i got off ebay, layed the board on newspaper, conect the cpu, mem, hard drive and psu, and used a flatblade screwdriver to short the power pins to switch on and sat back waiting for the post screen, while staring at the blank screen for 20-30 secs, then SHIT, unplugged the power cord from the psu - in all this time, i had forgotten to install the heatsink/fan. D'OH! fitted the hsf, and powered on, nothing. works fine with a p1-200, but can run at 366 with the right chip(K6-2)
