I've had bad experiences with NTSC machines running PAL software, and most amiga software is indeed PAL.
Others have found ways around it, so there's solutions.
What do you want to use your miggy for?
Not really anything of any import... I mostly want to network it with my pcs basically just for the Hell of it. I really enjoyed my Amigas back in the 90s and just having fun messing with it. Not really too interested in Games, just to fiddle with. Plan would be an 030 board or better and OS3.9 and as much eye candy as I can squeeze into it, making it as modern looking as possible. Once again just for the Hell of it..
(And thanks for the info BBOND, much appreciated.. )
