Knowing nothing about the Atari series, I decided to look at the schematics of the Atari Falcon.
Oh boy, that's a 16-bit data bus architecture for sure. D0-D15 just dangling in the breeze on the 68030, and the FPU even wired up for a 16-bit bus.
I mean, even commodore's first 32-bit motherboard (A3000) at least had 32-bit RAM; they even put a bridge circuit so that the processor had 32-bit access to (admittedly, slower to access) the 16-bit CHIP ram.
I mean, it's not the end of the world, any loops that run in the 68030's (admittedly small) cache would probably run full speed. But wow, no 32-bit RAM on a processor with a 32-bit data bus...
