What about the Jaguar? That's a '64-bit system' even though the microprocessors are only 32-bits wide...
I will concede that if the machine can only transfer 16 bits of data in one operation that it would be considered a 16-bit machine. But the CPU in the falcon can perform 32-bit operations on data, and what about the DSP? Can't that access 32bits of the bus?
You've confused me and destroyed many of my thoughts about the falcon :(
