PAL-NTSC Switching

[Darrin]

I have an ECS A2000.  It was originally a NTSC model, but it had the Agnus that was capable of both PAL & NTSC modes.  If you have the same motherboard revision then there is a jumper that needs a trace cut to switch it from NTSC to PAL and if you fit a switch to the jumper pins then you can use that to toggle between the modes prior to switching it on.

I'll see if I can find the info on it.

Personally, I set mine to PAL and left it that way.

Edit:  I found this note on the BBoAH:

Jumpers

These setting come out of the manual for an Amiga 2000 Revision 4.x and is compliant with Rev 6.x Amiga 2000 boards as well.
 
J102

This jumper if available configures the A2000 for NTSC, or PAL operation. Agnus 8370, 8372A, 8372AB for example, support switching between NTSC and PAL. Rev 6.4 motherboards and possibly later revisions come with an 8375 Agnus by default which does not support switching. It was made in in separate versions for PAL and NTSC

All my miggies have switches on the back (leading to the according jumper) for selecting PAL/NTSC - just toggle & reboot. Yes, this can also be done when powered up, the effect is on reboot only, however.

That's nice to know.  I was always worried whether it might do something nasty to the machine.

is this toggle switch in the back of my NTSC A2000? Where?

If you're talking about the jumper I mentioned then you'll find it on your motherboard inside the case.  You'll need to take the drive bays out IIRC.
