This is likely a very dumb question, but I got a PowerMac G5 without a power cord and was wondering if I could use any power cord with it (I have a couple of generic power cords that fit). Is there anything special about the apple power cord?
I have a special pry bar that came with a 68040-50 upgrade for my Q950. Very strong flat thin metal slightly curved at the end with teeth that fit in between the pins so it is easy to pop a CPU out without bending a pin.
Thanks guys very helpful. I traced D24-D31 back to the ROM and PDS slot, everything fine there. Also fine were RA0-8 and the other lines RAS/CAS, etc back to the PAL ICs.
Were there any others I should check?
Unless there is something else - then I guess either the 253 mux’s or a bad PAL. Are PAL ICs known to die? Long shot but there a reliable source for replacements? seems unlikely 30+ years later anyone Is burning fresh ones...
Further info, my board is p/n 820-0260-10. It looks like an early revision as it has a factory cut trace to UI6.
