I have an Apple /// that beeps maybe 4 times a second when powered on and displays a set of horizontal, non symmetrical bars on the screen. Sometimes an ascii character or two will be in the center.

So...

Hi, I recently had a similar issue on 2 of my A3 and in both cases the power supply was the problem; but I could not repair it until now...

It sounds like a video rom error... check to make sure that every chip is seated; and then check for burst capcitors, and such, in the power supply.

I ran this query past a friend of mine (http://www.6502lane.net/2010/07/27/apple-panic-oh-yes/), who replies:

"That's not a normal diagnostic-type error, but it looks like the right path to start troubleshooting: if that were me, I'd start with the power supply and then the video ROM, as suggested in the thread."
