(It has come to my attention that this line is NOT(?) nescessary!) Help help but to add my little story as well. About 4 weeks ago (yes! a month ago) I tried to power up one of my C64's as I usually do. After a few seconds I noticed that it had not initiallized so I knew something was wrong. After the usual obvious checks (is it plugged in, etc...) I got out my trusty multitester and looked at it and noticed that a power line had 3v when it was supposed to have 12v! For many days I could not find the source of the problem, so I kept on looking and eventually decided to replace components at random (remember this ?-) and that's where I found the source: It turned out that a diode was put in backwards (wow!) in the power supply but it was able to function for 9 months. Eventually the diode died and began to act as wire. When presented with a choice of going through a diode of a wire there is very little to choose. The 7812 got no current and half of the system did not have the right voltage... Who said micros are "simple"? -- Jose A.
