If you want to use an NTSC Amiga Down Under (or anywhere else PAL is the
common system) and you have (1) an NTSC monitor, like the US 1080, and
(2) a voltage converter that'll give you the 110V of the USA versus the
220V of most PAL countries, you're ALMOST in business.  You'll still have
two problems.  The first is that the CIA chips have timers in them that
count 60Hz pulses.  When you feed these parts 50Hz, your timing functions
will be off.  Version 1.2 of the OS will cause correct timing on either a
PAL or NTSC Amiga, but I'm not certain if it'll correct for an NTSC machine
running on 50Hz.  The other problem will only arise you you're using 
flourescent lighting.  These lights will flicker at 50Hz, where your
NTSC monitor will flicker at 60Hz.  The result of this is that you get a
beat frequency of 10Hz on the monitor, which can be annoying.

There is a PAL version of the Amiga, which I believe is either selling or
soon to be selling in Europe, and probably Australia shortly after that.
This includes PAL support in the Kickstart, 220V power supplies, PAL
monitor, etc.

   A quote usually goes here, but its currently being rennovated.

	These opinions are my own, though for a small fee they be yours too.
