Hi Cory,

this is also a point, which I like on the 8051:

I can write code for the little AT89C2051 and the same hex file runs also on the big DS80C390.

But the different PICs have always different architecture (instruction set, memory architecture, word length).
So any hex file runs never on a different PIC member.
And most code must be rewritten for using into another derivate.
Maybe, with tons of assembler switches you can write software modules running on different derivates.

On the 8051 family the assembler wants never to know, which derivate you use, any written software can be reused on any other 8051 derivate.
Naturally, if the software access build in peripherals (ADC, DAC, I2C, CAN) these peripherals must exist.
