Title: PAL Amigas with US (110v) PSU...
Post by: blakespot on August 16, 2014, 10:52:35 PM
I am selling a few Amigas in pieces and want to get an A600 or A1200, expand it somewhat, and run with that.

I am in the states.

WHDLoad will be the source of most of my program launches, but anything I want to boot off floppy (or a floppy emulator) is going to be written for PAL. This time around I don't want the hassle of having to run Degrader first to get the system to PAL timing before booting the floppy.

If I buy a Euro / PAL Amiga 600 or 1200 and use a US (110v) PSU, I understand that this will work. What I am wondering, is will the Amiga retain system PAL timing even with the 60Hz PSU? I will be using it with a 1084S that I know handles 50Hz fine, and an Indivision.

...or is it trivial to wire an NTSC Amiga 600 or 1200 to run in PAL by default?

Thanks.

Hmm, interesting question as the transformer converts alternating current (110 vs 220 volts) at some frequency (50 or 60 cycles a second) to direct current at 12, 5, and -12 volts which is constant with no variation.  Now let's see, is there a way to have DC current with a frequency of 50 or 60 cycles a second.  Er, No.  Since the graphics chips (Agnus/Denise & Alice/Lisa) generate a PAL signal from DC current you should have no problem.

I think you you will be fine.

afaik the psu has no impact on the performance of the amiga whether its pal or ntsc.

Why not grab one of these?

These are 110 power, PLUS they are built for an a500, which means they'll more easily handle the power requirements of an a1200 with any potential upgrades.
