I’ve heard people describe the Amiga 1000 as a 16 bit computer a few times lately and it always catches me off guard. It was usually, defensibly, referred to as a 32 bit computer at the time.

Some of its implementation details were 16 bit, like the data bus and ALU, but they were largely invisible to users and programmers. Assembly code used 32 bit math instructions, even if the CPU executed them in 2 steps. It had a flat 32 bit address space, although only 24 address lines were implemented (kind of like how not all 64 address lines are available on a 64 bit CPU today). Registers were 32 bits wide. And later 68K CPUs could run A1000 software on pure 32 bit CPUs natively with no emulation or trickery.

Credit it with those extra 16 bits. It earned them.
