In addition to a different Agnus chip, as Dale Luck has
pointed out, a PAL Amiga will need some different passive
components to support the MC1377 used to generate composite
video. I don't have a data sheet at my fingertips, but am
sure that the 3.58 MHz crystal will need to be replaced
with a 4.43 MHz crystal for PAL composite video output.
It would appear that Agnus is responsible for video timing,
so a PAL Agnus would mean the RGB outputs had the PAL
scan timing. None of this could be accomplished by software.
