I wonder why couldn't Intel simply introduce single 'offset' register for apps ported from 8080, and make all other registers 20-24bit. Why bother with 4 different registers and all that segmentation nightmare?
Very few benefits to a clunky 24 or 20 bit word size; now it costs more and is a bizarre boutique architecture in a world where it needs to compete with 8 bit Z80s and 6502s.
