The
Enhanced Chip Set (
ECS) is the second generation of the
Amiga computer's chipset, offering minor improvements over the
original chipset (OCS) design. ECS was introduced in 1990 with the launch of the
Amiga 3000. Amigas produced from 1990 onwards featured a mix of OCS and ECS chips, such as later versions of the
Amiga 500 and the
Commodore CDTV. Other ECS models were the
Amiga 500+ in 1991 and lastly the
Amiga 600 in 1992.
