So the PAL c64 has a different type of power supply. A european two prong type. Does anyone know what it will take to convert power to American 120V? I need to start planning on how to get this machine up and tested at the next workshop June 30. -- ========================================= Jeff Brace Vice President Vintage Computer Federation
FWIW, C64 power supplies are notoriously terrible and almost all of them produce over-voltage by now; essentially frying the computer because Commodore thought fuses and such are too expensive. The power supplies (iirc) aren’t serviceable either. There’s a bunch of instructions for making your own supply, and there’s sellers of new power supplies as well. (I have a European PAL C-64C and use a 3rd-party supply.) Best, Thomas

Tony gave us a step-down adapter for the BBC Micro (240). Tony: will that same device work with Jeff's PAL 64?
Yes. I use a step down 240 to 120 for using a PAL C64 in the US. On Sun, Jun 17, 2018, 6:13 PM Evan Koblentz via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

If it's a two or three prong European plug he should be able to just plug it into the step up transformer I dropped off. It is designed to handle several different European "standards" Just make sure you set it to step up the voltage and not down (it's a switch and some jumpers to make changes so you'd have to go out of your way to screw it up.......fortunately we are talking about jeff and not Evan ;-) Tony Sent from my iPhone

You want the transformer to step up the 120 it's being fed to 240 for the c64 to consume. Tony Sent from my iPhone

I use an American power supply on my PAL C-64. No issues.

There is one "Gotcha" to be aware of if driving a PAL c64 from an NTSC psu in the USA: Because the 9VAC input to the c64 is derived from a linear power transformer, the TOD "RTC" interrupt to one of the CIA chips will be at 60hz, not 50hz, so any software which depends on that "clock" circuit incrementing at 50hz will be wrong.

As long as everything south of the step up/down transformer is consistent (all PAL or all NTSC) you'll be fine. Otherwise yes you'll have to replace the crystal and the VIC II chip if you want to use a NTSC monitor plugged into a regular NorthAmerican plug, with a PAL machine plugged into a step down transformer. In the case of my P500 exhibit at VCF whatever I replaced the crystal and VIC-II chips so I could use any display plugged into a standard socket. Oh and remember you'll need a PAL 1541 disk drive also attached to the step down transformer drives are also incompatible b
