    I was at school today doing some assembly programming on a god-forsaken 6809 processor. The board is external and connected to the computer via the serial port. It is also connected to a molex connector from the computers PSU

    So after I was done, I started to screw around a bit, and decided to short some contacts underneath the board (i know, i know). So, I expected the board to restart, but instead the computer it was connected to fully shut off. I pressed the power button, nothing. Again, still nothing. Fearing that I broke a school computer, I pulled the computers plug from the wall socket, hoping for a miricle. Sure enough, the computer springs back to life.

    So, what do you think, how did the computer come to a near death scenario? And what havok will I unleach with this newfound knowledge?

    I suspect that you may have shorted or overloaded one of the power supply outputs from the computer. This may have tripped an overload sensing circuit in the power supply that shut down all of the power outputs. The overload sensing circuit may have needed complete removal of the AC power to reset. The power button on the front of a modern computer does not really kill the AC mains input to the power supply.

    FWiW, My first home computer was as Radio Shack Color computer that was based on the 6809. I sold it in a few years and got the newer Color Computer version that came with 64K of RAM.
