MegaChip A500 Install

I had a request to install this MegaChip on a REV 5 Amiga 500 and take care of the 3.1 ROM kickstart socket mod as well while I had it. The process was fairly straight forward. I followed the original manual for the MegaChip for a REV 5 by cutting and relocation the JP2 jumper and then had to cut a single trace over near the trap door RAM header. You then need to attach a jumper wire from the board to pin 36 on Garry or pin 48 on the 68000 CPU socket. Once done I desoldered the original Agnus socket and replaced it with this newly made adapter board with 2MB and the 8375 Agnus on it directly to the motherboard. This will allow a 68000 socket accelerator like the Vampire 500 and others to fit over the Mega Chip. I am quite pleased with the final results. If you are interested in one of these you can pick one up over at Amibay following this link: http://www.amibay.com/showthread.php?101224-Megachip-for-A500-A2000-and-CDTV-(rj1307-project-Poland)
