ECS super hi-res palette limitations

I understand the maximum of two bitplanes due to DMA bandwidth limitations (twice the speed of hi-res leaves half the amount of data per pixel), but why is the palette limited to just 64 colours...

Hardware abstraction doesn't come for free, and it's only natural that early attempts, despite being extensible, were not as performant as direct hardware access on the relatively slow CPUs at the...

It's worth mentioning that this is only relevant if you modify the motherboard, as the Agnus isn't connected to the trap door memory otherwise.

From what you say, it seems like we agree that Intel had CISC expertise, and not only "at that time" (mid-90s). They wouldn't be able to design or produce their CPUs otherwise. :confused
