- I assume you have the fat agnus... (you must :)
-
- You may be able to figure this out for yourself if you have the schematics.
- (They should have come with your "Introduction to the Commodore Amiga 500"
- book.) Find the page that has Agnus on it (may be "FANG" or "Fat Lady"
- depending on version.) Find pin 44 (Labled "Test" or "NTSC/PAL") and trace
- the lead to the jumper it connects to. Then find this jumper on your
- motherboard and cut it. Install a wire to the lead coming from the
- chip and another to a ground. Put a switch between them. When grounded
- it's NTSC and when open it's PAL. Good luck.

- As with anything hardware, I take no responsibility...
