The heart of the Amiga, Agnus was designed by Jay Miner, Joe Decuir, Ron Nicholson, Edwin Chu and Dave Needle. It provides a memory controller, address generator and video sync signals. The chip’s architecture remained relatively unchanged throughout development aside from the ability to address 512K of RAM and the addition of a line draw circuit, which was suggested by Dale Luck.
Early versions of the chip are also known as 4701.
