> 16-bit Commodore Amiga era

The Motorola 68000 was a 32-bit processor. What Commodore Amiga was 16 bits?



Fair enough. As someone who was alive in the 80s, I remember first generation home computers (ZX Spectrum, Commodore 64 etc) were (correctly) called 8-bit, and the second gen (Amiga, Atari ST) were colloquially called 16-bit.

The CPU was 32-bit but the earlier Amigas (A1000, A500) and STs had 16-bit data buses. That was probably why.

... but not entirely. The registers were 32-bit but the ALU and data bus were 16-bit.

The 68020 was the first 68k chip that was 32-bit without having to qualify exceptions for different parts of the architecture.
