OT: PowerBook processor

[Terry Barnum]

Hi Jim.

Yes, I do get a chime on boot. Three in a row in fact. Then after a  
long pause the glass break sound. When the machine started acting  
funny a few months ago I replaces the PRAM battery but the problem  
remained and got worse until now, it won't boot at all.

My wife took it into UCSD's Mac repair and they diagnosed it as a bad  
processor card and wanted nearly $400 to replace it. I thought I'd be  
smart and get a faster, Sonnet processor card. I didn't read closely  
enough on Sonnet's site where they say you need to boot with the  
original processor and run their software before installing their card.

My dad is kinda going through withdrawals. Not pretty.
