- Nope. The difference between ECS and OCS is the super Denise. The super
- denise can display more resolutions and higher color depth. You could get 1
- meg of chip under OCS with the Fat Agnus. The Fatter Agnus of ECS was a 2 meg
- chip Agnus and would support up to 2 meg, altho many systems shiped with 1
- meg. AGA is the 256 color chipset. Also, multisyncing screen modes from
- 15khz to 72khz. A3000's have either 15khz OR 31.5khz depending on the port.

-
- Close. OCS= 512k to 1 meg. ESC= 1 meg to 2 meg. AGA = 2 meg and 256
- color.

- ^^^ 1 meg... :-)
