Does THAT make it a 16-bit processor? If "processor" means "something
that processes something", and that processor can "process" two 16-bit
values in a "single operation", does that make it a "16-bit
processor"?
See, it's not all that cut-and-dried. I think we need to defer to
what is "commonly accepted" amongst the learned. Everyone knows the
8080 is an 8-bit processor and the 8086/8088 are 16-bit processors. But
you CAN, if you try hard enough, define them differently.

Well you've got to admit, it does depend on
how you look at it. The 8088
has an 8-bit data bus and it does two bus cycles to move a 16-bit value.
You know...just like an 8080. ;)
Well, the 8080 can't do a 16-bit by 16-bit multiply to get a 32-bit
product, so that's an obvious difference.
