And thusly were the wise words spake by Seth Morabito
I'm sure most everyone who has ever used a C64 is aware of just how
phenomenally bad the Commodore power supply is. I have only one C64,
but both of my spare Commodore power supplies have now failed, taking
a few 4164 RAM chips with them (thankfully, I have replacements!).
Does anyone know of a commercially available replacement power supply,
before I go off and build one? A linear supply would be trivial to
design, but I've never done a switching power supply, which I suppose
would be greatly preferable. The trick with the C64 is that it
requires both 9V AC and +5V DC. (I've considered frankensteining
together 9V AC and +5V DC wall-wart adapters onto the same DIN-7
cable, but it just feels so very very wrong).
I'd love to hear from other Commie fans who've solved the power problem.
Use a C128 power supply, but replace the C128 power connector with one
from a C64 power supply, making sure to connect the
right wires to get
the right voltages on each of the C64 power pins. Then you will
have
an heavy-duty power supply that can handle a SuperCPU, RAM expansion,
etc..
