Well the 40 year old architecture that you are talking about was
E-mode Alpha or something preceeding even that.Since then there has been
E-Mode Beta specification which is has been emulated on the x86
architecture. This was followed by E-mode Gamma. E-mode Delta originated
somewhere in 1993 or 1994. This provided good improvements among other
things in size of the stack and imrpoved procedure entry times.
