It's not clear to me if the problem is with your CPU or with your A520. The "hand" wasn't animated. It was a simple still picture of a hand holding a disk. Later ROMs (2.x) used an animated diskette inserting itself into a floppy drive. I don't recall ever seeing blue. *Green* was the one you saw most often - typically caused by the Agnes chip working its way out of its socket (later units had a small spring-steel keeper over the top of the chip). Green meant that something was wrong with accessing CHIP RAM (*most* often a bad/loose Agnes, but not exclusively). The other common color was gray/white which just meant that the lowest level stuff worked, but it wasn't loading/running OS code. I have seen Red and Yellow, but they aren't very common. Black, of course, with no color shifts at all, means that nothing is happening (bad PSU, bad CPU, bad ROM...) That sounds right (I never had a 500+) Is is possible that the "blue" you are seeing isn't really a true "blue" (as in it's a black screen with the colors/brightness turned way up; or more of a deep blue, almost maroon, which could be the 2.0 background color with no disk image/text on it?) If it's a primary, saturated, bright blue (bluer than the desktop of a Windoze machine), then it might be a signal from the ROMs that something is wrong. A darker, muddy blue is probably something else. If, for example, the Denise chip is bad, or the external network that converts its 12-bit color bus to analog signals is bad, or the A520 is bad, perhaps it's a white screen with only the Blue component showing. Describe how the power LEDs flash - that tells a story, too. -ethan
