PAL on A2000

[jdupuis]

AFAIK 4.x boards only came with the 8370 or 8371 (fixed) Agnus.  It wasn't until the 8372A that they became software-switchable.

In any case, back to OP's original question, no.  Not just a simple jumper.  Use Degrader or WHDLoad to make it easy on yourself, unless you want to make it be PAL 100% of the time.  

Degrader works quite well without any MOD. It works wonders for me on my 1 MB A500. Just simply shutdown and your Amiga returns to NTSC. WHDLoad is awesome as well. Listen to Mike!

Cheers!!
