Amiga Original Chip Set (Agnus and Denise)
The custom chips that made the Amiga what it was. Agnus holds the blitter and the copper display coprocessor and arbitrates memory; Denise generates the display and the sprites. Both work directly on Chip memory without involving the CPU.

Editorial notes
Paula, the third custom chip, handles audio and I/O and is not modeled here because the catalog records processors, graphics and memory only. The original Agnus reached 512K of Chip memory; Fat Agnus and later the Enhanced Chip Set raised that to 1 MB and 2 MB.
