Does anybody know why the site is called 16-bits? Aren't trackers an expression of the first 32-bit computers?
The Motorola 68000 was a 32-bit processor. What Commodore Amiga was 16 bits?
... 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.
The CPU was 32-bit but the earlier Amigas (A1000, A500) and STs had 16-bit data buses. That was probably why.
