There's a guy on Amibay (Tuxbar81) who designed a replacement for the Megachip for A500/2000, he's selling them assembled or as kits.
Two batches have been sold already, pre-orders for the 3rd are currently open.
Look here:
http://www.amibay.com/showthread.php?92591-Project-of-Megachip-for-AmigaWhat's the difference between a PAL and NTSC Megachip (besides one being PAL and the other NTSC). I'm looking to increase the chip RAM in my Amiga 2000 and, unless I'm wrong, NTSC Megachip is fairly rare (and therefore expensive when they do come available.. I don't watch amibay 24/7 to express interest if one did show up there). PAL Megachips, however, seem less rare. Since I use a graphics card (VA2000/CX) and if there is no difference in motherboards, what is stopping me from installing a PAL Megachip? I know the VA2000/CX works with PAL.
