Cyberstorm PPC Problems

[mike-]

Hi,

Well, i got my CPPC back from repairs. I bought it broken and preyed it might be fixable.

But the first thing i noticed was that it didn't map any memory, ( oh well i thought, might be that its incompatible ). Then i discovered that the ppc wasnt functional.

So far I've tried flashed it up, and tested it with the ppctest disk, but the amiga only reboots when i try the warpup test, and says ppc.library not loaded when i try that test. Any ideas on what might be fried?

Cheers
Mike

I have the mediator but I've pulled all that and use the standard zorro card now that im testing/diagnosing. It's got the 3.1 room too btw. I've tried all sorts of memory. EDO non edo old 8 meg stuff, you name it.

Hm, re-kick ay... hmm

Wouldnt it need memory to kick to?

I have some double sided 32 mb bricks i hoped worked, but i've since pulled every brick from every old pc from miles around ^^

But that the memory controller is bust is what i "hope" is wrong too, if its the ppc its gonna be hellish.

No, it wasnt JJB, but i sent him an email yesterday, and its going to France asap, hopefully.

I noticed that the chip to the far right ( MACH231SP-15YC ) above the 0-1 bank gets frigging hot tho, so I've done some radical fan mods and just placed it over there, which seems to work.

Hm, can anyone tell me if the cppc ppc can work without accel ram? That might explain why its not working.

i see a broken/half broken path going from one of the CY74FCT543ATQC chips, near the memory, i cant find any info on the chip tho
