PAL grounding, CPU replacement, >etc? I've had this happen on two A1000's that I've owned. It also involved the old CLtd 1 Meg boards...of which one I am still using. The first time it happened, I sent it off to the dealer. He told me he grounded two weak PAL chips to the two non-weak (!) ones...and charged me a healthy 65 smack-a-roos. When the second computer did the same thing, I wasn't surprised. Rather than spend the bucks again, I decided to take it on myself - with the help of a recent article in (what's the name of that magazine?) a magazine. It showed how to connect jumpers from the good to the bad chips (however their diagram was screwed up - what IS the name of this magazine?). It worked fine. I later had the first 1000 apart, and the dealer did exactly the same thing I did. It's a fairly simple procedure, and maybe somebody else here could explain exactly what pins need the jumpers, as I can't remember right now. ---------------------------------------------------------------------------- Tony Poole Traverse City, MI USA EMail:tony@irie.ais.org ____________________________________________________________________________
