Hi Amigans,

I'm looking at upgrading my NTSC 2000 to 2mb chip either with this hack or simply with a Megachip board, but 2mb NTSC Agnus' are nearly impossible to find whereas PAL ones are more common.

Are there frequency issues with using a PAL Agnus? After all the motherboard is the same in NTSC and PAL versions anyway right? My machine was originally PAL and I've just swapped the jumpers and crystal so I can run a Video Toaster.

If I try the hack - are there any 8375 Agnus' that are pin-compatible with the 8372B?

Thanks in advance to anyone who can help!
