Most PSU's only have 4 pins Originally they had all pins in the plug but then came the CR craze and original PSUs started to have only four pins with an inadequately pronounced orientation notch, which to make things worse didn't expand over the whole length of the plug. Especially didn't extend to the edge of the plug, allowing people to partially insert the power plug at arbitrary angle and then rotate it until the pins aligned with the holes. With all pins present that wouldn't be much of a problem as the correct orientation would still be the only one where pins would align with the holes. Four pins AND lack of the properly pronounced orientation key on the power plug resulted in a flood of C64Cs, fried beyond economically viable repair, at my doorstep... > and some > of them have so wobbly plastics that you don't even need much force to > force the connector in the serial port even though the pin positions > doesen't match.

That happened sometimes too, albeit far less often, I'd say. People plugged it in the *correct* socket but not correctly oriented. And it's hard to blame them much for that. -- SD! - http://e4aws.silverdr.com/Received on 2018-09-14 13:00:04
