Do you have to replace Agnus with another version to do the 1mb alteration?
Depends on which Agnus you have. As I understand it, you need at least an 8372A. I think some A500s with 6a motherboards were sold stock with that chip and just need a little jumper modification to enable 1MB, while others need the chip and the jumper. As far as I know, no Rev 5 or earlier A500s had the 1MB Agnus stock.
I remember being disappointed that my Rev 6 A500 didn't have the 1MB Agnus. Installed the chip, cut 2 traces (IIRC) and along with the 512k "trapdoor" board I had one full meg of chipram...whoooooooeeeeeeeeee, all the games I could play then:-D
