All the project settings are shown on G4.ĬompileC "build/AudioOverload.build/Build/Audio Overload.build/Objects-normal/ppc/mac-file.o" "/Users/richardb/Documents/Programming/Emulation/Audio Overload 2/Project/./mac/mac-file.c" normal ppc c .4_0Ĭd "/Users/richardb/Documents/Programming/Emulation/Audio Overload 2/Project" The Intel machines, on the other hand, can run Windows natively and safely. They also run my OS 9 programs (sadly, many good apps never made it to OS X, they either died or went to Windows), making the G5 looking even more useless and pathetic. No, I think I just get a cheap Intel machine, and keep my G4 MDDs for work. The 8 GB of RAM wasn't too cheap either back in 2005. That was a lot of money that went down the drain seeing how the PPC programs I wanted to use on it either cancelled or dropped support, also thanks to the PCI/PCI-X/PCI-e switch around that time. If Apple would have just announced the switch sooner I wouldn't have invested in that machine at all. G5 support works for me, and I probably get rid of that machine anyway before Snow Leopard arrives (which just may drop PPC support entirely according to the rumors). Well, being unable to provide any more info as a generic user with no coding know how at all I'll just let this rest. Knowing you didn't and never would specifically target ppc64 it's indeed a complete mistery. If so, I think that applying 12Vdc, will not harmful to the unit while eradicating the hum and ripple problems.Mac-mini:~ l66$ lipo -detailed_info /Emulation/Audio\ Overload\ v2.0b9/Audio\ Overload.app/Contents/MacOS/Audio\ Overloadįat header in: /Emulation/Audio Overload v2.0b9/Audio Overload.app/Contents/MacOS/Audio Overload It is possible that U2 is used only to protect U3 from transient, leaving it as main regulator.īut, looking at the PCB parts and tracks, I've the feeling that it is a switched capacitor part to generate the negative voltage required by the amplifier, leaving U2 to supply the positive side. The only doubt is U3, that I can't recognize from the image. Thus feeding with 12Vdc should not give problem for this regulator. Since it requires 2V minimum of dropout, it is always working in saturated mode, thus all input ripple can be found at the output. Thus actually it never 'regulates' since the nominal 9Vac input (considering the voltage drop across the bridge and the crest factor across the capacitor) should give something less than 11V (often the transformers have an actually higher output voltage than nominal that drop on load). After that there is a linear voltage regulator from whom I'm a little puzzled. The unit has a classical diode bridge rectifier. Maybe the AC hum can be avoid supplying the unit from a DC source.
