-
- It's not "all or nothing". Using the same chips speed, but having dual access
- would already mean to avoid the syncronization with 7Mhz chipram bus clock.
- And, whatever is the amount of DMA activity, the CPU wouldn't be slowed down.
-

-
- The ram is ok, it's Alice that runs the chipram bus at 7Mhz.

-
- Let's do also this way.. any way is good to improve the current speed.
-
- It seems that Escom/AT considers the actual AGA chipset as perfect, or anyway
- "adequate". That's why the Amiga games market doesn't exist anymore.
