The Enhanced Chip Set (ECS) is the second generation of the Amiga computer's chipset, offering minor improvements over the original chipset (OCS) design.
Another version was developed around 1994 but was unreleased due to Commodore International filing for bankruptcy.
[4] The ECS Denise chip offers Productivity VGA output (640×480 non-interlaced) and SuperHiRes (1280×200 or 1280×256) display modes (also available in interlaced mode), which are however limited to only 4 bits on-screen colors.
The Productivity output required a multi-sync monitor.
It also allowed for a greyscale resolution of 1008 x 800 pixels with the A2024 monitor.
