Hello everyone i need a guru. Im putting together a long awaited berzerk. But when i power it up all i can get is a loud quick beep and the monitor shows some weird kind of pattern maybe like a hand made multi colored rug. Looked through other threads but didnt see anything battery looks good but didnt meter it yet. I dont want to go in blind. So waiting 4 some input before i screw something up.


Thanks allen
 
you have a problem with your ZPU board. So far on the ones I've worked on, your first beep is loud, then the volume circuit kicks in and the rest or quieter.

You should have a total of 8 beeps, and led flashes on the zpu board.

The berzerk manual has a decent trouble shooting section, that should help you get your Zpu board up and booting.
