Was the X86 family meant for pascal type languages?
Other than the small model, every thing is a hack.
It was generally agreed on many of the new features needed.
Motorola abandoned their previous code base, and designed the 68000.
Intel realized that they could "get away with" just adding patches and
kluges.
Yes, a "flat" memory model is simpler.
For getting started, you can set CS, DS, ES. and SS to the same; org your
program at 100h.
