Now I am confused. I always thought that ECS Amigas, with the exception of the A3000, only had a 1mb Agnus, with ECS Denise.... Now Im getting conflicting information. From one source I am being told that a 2mb Agnus will NOT work in an A2000 or A500 unless either installed in a 2mb chip...
Hallo, yes you need a Super Denise/Hires Denise (MOS 8373 or CSG 390433-02) and a Super Agnus (MOS 8375 or CSG 318069-16).
For the Amiga 2000 you need also expansion board for the adaptations to the Super Agnus and the 2 Meg Chipram. Something
like the "ACE2b" from INDIVIDUAL Computers, the "A500/2000 2MB Chip RAM Mod" from Matt Harlum aka LIV2 or others.
