The Amiga 4000 motherboard includes a non-functional jumper that anticipated later chips and is labeled for 8 MiB of Chip RAM—regardless of its position, the system only recognizes 2 MiB due to the limitations of the Alice chip. [3] However, the software emulator UAE can emulate an Amiga system with the design limit of up to 8 MiB of Chip RAM ...
