- The 3000 was the first machine to introduce ECS. It was years later that AGA
- was produced in the 4000. Are you thinking about OCS?

- OCS- Original Chip Set- Resolutions 320x200-640x400 upto 512k chip, used in
- A1000, early A500,A2000
- ECS- Enhanced Chip Set- Resolutions as OCS plus the productivity modes, upto
- 2 megs chip ram, used in later A500,A2000, A500+,A600,CDTV, introduced in
- the A3000. ECS could be seen as a kind of hybrid of OCS and AGA.
- AGA- Advanced Graphics Archetecture- ECS modes plus all the good stuff! used
- in A1200,A4000,CD32
-
- There are both 1MB and 2MB capable ECS Agnus chips. Both can use less than
- the maximum. Alot of the A500's with only 512k really have an ECS Agnus.
- The ECS Denice is not required for 1MB chip ram, only for the ECS screen
- modes.
-
- The reason an A2000, or A500 can't get 2MB of chip ram is that the
- motherboards were designed before ECS. There aren't enough address lines on
- the board to use more than 1MB of chip ram. The MagaChip puts the extra
- chip ram on a board with a 2MB capable Agnus chip.
-
- I'm not trying to be a d*ck, I'm just trying to clear up why he said ECS.:)
- The people with OCS can't play the game because they CAN'T get 2 megs of
- chip ram.
