The Amiga 500 I had made that even more awesome: there was +/- 12VDC on a couple of the pins of the serial port, and the parallel port had +5VDC. Hot plugging was very dangerous as a result. The crazy part is that the Amiga 1000 had power on different pins. Modern systems would have PTC fuses on those power pins to reduce the likelihood of damage, but not 1980s computers!
