A500 failing?

[hotdiggity]

Your mention of faulty RAM led me to try something. I pulled the extra RAM chip out of the bottom and tried booting it up. All I got was solid colored screens and nothing else. It wouldn't boot from a floppy.

I put the RAM back in and I got similar color screens (I think it was dark grey, grey, then white), then for a brief second a black background with garbled red text (it didn't stick around this time, it flashed away after a second).

So then I pulled the A520 off and plugged in via B&W again. I got a readable error message: Software Failure. Press left mouse button to continue. Guru Meditation #00000003.00C01570. I pressed the left mouse button and surprisingly, it booted off of the Workbench disk. I shut it off, plugged the A520 back in, powered it on, and it booted to Workbench again, in color. I don't know what happened, but it's working now. I kind of wonder if it will remain that way, though.

Ahh well, time to play some Firepower!

P.S. I looked up the error code at this site and apparently the 3 means Address Error. My question is: what does Address Error mean?
