Greetings, I'm making my first posting here. I've been pondering the proper power supply sequencing for a SID chip.
In some regulator arrangements the 12V supply could come up before the 5V supply comes up, how's this arranged inside a C64 supply brick? Just a 12V linear reg followed by a 5V linear reg, or do they have separate transformer windings?
There's no hints in the datasheet of the chip; later datasheets tend to be more explicit about supply sequencing. I've only had the chance to study the usual circulation of old datasheets on the net, so I might have missed a more finished version of the MOS 6581 datasheet somewhere.
