- My old A500 has 1MB Chip RAM but doesn't support Productivity or Super-Hires. And no, having Kickstart 2.0 doesn't equal ECS - an A1=
- 000 can use KS2.0 if you know what you're doing.
-
- ECS is, more or less, three things:
- o A big Agnus, 1MB or 2MB.
- o Super Denise. This is for Productivity and Super-Hires.
- o Kickstart 2 or above.
-
- It's a FAR bigger jump from ECS to AGA than from OCS to ECS; these days, yes, most software places do seem to use ECS to mean "a 1MB=
- Agnus," to the point where OCS and ECS are basically synonymous with each other and with "not AGA."
-
- I know of only three features of ECS that aren't in an older machine with a big Agnus: super hires, Productivity, and the border-bla=
- nk mechanism.
