Hi, I would be keen on a 2A but I would need to confirm this would be for a PAL build, and the PSU listed in the BOM states 90v-264v which I have not seen before, this would be OK on our 250v 50Hz in NZ?. Cheers.
PAL/NTSC: You can call the option of the PAL/NTSC. The bonus part of this machine is that with the addition of a few chips and a crystal you can have BOTH! It is hard wired that way. All you have to do is swap out the *socketed* crystal with the opposing crystal and swap out PAL/NTSC Atari LSI chips with their counterparts. It is truly the first Atari (real iron) that can do both in the same unit with a MINIMUM of effort.
POWER SUPPLY: The benefit of the power supply is that it will work on all known country voltages/frequency schemes whilst supplying steady voltage necessary for the power board.
Tl;dr: Yes, it will work as a PAL machine and work well in New Zealand.
