That's what I thought too. And in my mind, that must be the reason why the powersupply's TIC pin voltage stayed the same before and after the 230V modification.
Before the mod the USA spec 3000 was powered by a professional 230V -> 110 converter. On the label on the converter it says "Input 230V 50Hz - Output 110V 50Hz".
And I sound like a broken record but the oscillator is PAL, J200 is set to PAL. And still, SysSpeed says Power is 60Hz and the fact that games like Lotus 2 runs too fast, music plays too fast, that displaying PAL graphics is total crap while NTSC graphics are normal, must mean that the system is 60Hz.
I just don't understand how, other than that there must be a 60Hz TICK generator in the PSU, which does not care about the AC line frequency.
