Don't you rememeber the PC:s in the late 1980th? It was based on Intel's 80286-processor, and Microsoft's C compiler supported three or four different memory models, called things like "TINY", "SMALL", "LARGE", and "HUGE". Most of these memory models had different sized data and function pointers.
I don't think this is factually correct:
- tiny, small: code and data each 16 bit
- large, huge: code and data each 32 bit
- medium: code 32 bit, data 16 bit
- compact: code 16 bit, data 32 bit
So most of the memory models (66%) have same-sized data and function pointers, only few of them (33%) have them differently-sized.
In any case, I don't think Python supports 8086 segmented mode in any reasonable way today.
