You're full of shit. Get off your Amiga bashing horse already. Do you think Intel documents "the internals" of their chips beyond providing the same information Amiga provided about their chips?
You're just a troll.
The Amiga chipset did scale, there were multiple iterations, each far better than the previous, so I'm not sure where you get the crack that you're obviously smoking. Motorolo 680x0 architecture also did scale, there were multiple iterations and bumps in MHz and 16bit to 32-bit architecture. Macintosh computers of the day also used the same CPU, but were still stuck with black-and-white displays, while Amiga had thousands of colors.
The failure of the Amiga was clearly not based on the technical aspects of the hardware or software, nor the "scalability". Saying that is just completely ignorant.
