Hey folks!
I picked up a bread bin C64 recently, and I'm building a new power supply for it. I'm trying to find a range of voltages that are safe, sort of like a GO/NO GO gauge for my supply. All the sources of information I've found have been very conflicting (been researching for a few days). Some people are saying 4.7v-5.4v dc is safe, and 8-11v AC is safe. Others are saying 4.9-5.1 dc and 9v-10.5v AC is safe. Some people claim it should be dead nuts on 5v and 9v.
So what are the minimum and max safe voltages for the 5v DC rail and the 9v AC rail? Is it as critical to get the 9v rail close to 9v as it is to get the 5v rail close to 5v? How much headroom do I have here?
Thanks!
