I have a boxed C64 that hasn't been turned on for over 20 years

I thought I'd try to turn it on but got spooked by the requirements for the PSU

I understand it needs ripple free 5VDC 2-4A+ through a 7 pin din

Am I really going to blow the unit up with a switch mode, does it really need linear regulation?

What's stopping me using 2-3 LM7805s in parallel?
