I've got a CSPPC with a defective PPC chip.
This chip is producing A LOT of heat, and drawing insane ammounts of power to produce this heat.
I'm wondering if anyone knows a way to remove the PPC chip?
I'm aware this card came as a 060 only then called "Cyberstorm MK3", so there must be some way to just desolder the ppc and get rid of it.
As it is the thing causes diagonal striping on my screen, probably due to either zapping too much power out of the psu or by causing some kind of ripple effect, either way it has to go.

hmmm concerning problem prindeed, alas to tkae off the PPC chip would take some serious skill / equipment so as to not KILL off the 060 side of things.

Your best bet in all truth is Amiga Center France for the ppc chip removal, and if your wallet can take it, go for an 80mhz upgrade to the 060 as well :)

I have had dealings with Jaque and he is a really nice bloke to do business with, he will confirm with you before undertaking any work and post is always insured and tracked (thats the real cost right there)

Although not cheap, a damn good service! I would recommend him :)

On these OS4 days, I think is better you sell the PPC accelerator and buy a "pure" 060 accelerator. Or a swap?

I bet lots of people will throw you a very nice accelerator for that "crappy" PPC! :cheese

I don't have one the trade, BTW! :banghead

I would imagine there is a way to disable the PPC electrically, that an amateur could do, rather than desoldering it which would require a professional.

Taking the PPC crystals out in the top right corner might be enough to lower power consumption a lot? No clocks = Less power consumption!

All the power electronics for the PPC are in the top left corner. If you removed those correctly then it would not draw power.

But you'd have to talk to someone who knew a bit about CSPPC. Perhaps JJB would talk you through it.

P.S. Do not refer to these photo's as a reference for fine details as one is a CSPPC/040 and the other is a CSMKIII 060
