:The PDP-11 architecture has only 7 GP registers (since you can't
:really use the PC for just anything) but that's good for the times,
:and they really are interchangable, so I'd be willing to argue that
:it wins on that.
and having the PC as part of the general register set - even if it is a
bit limited in what you can do with it - is a huge design win; you can
lose an awful lot of PC-specific instructions that way. the SOAR used
such an idea, if memory serves.
:Similar, but in many ways quite different. I just had this
:argument (from a somewhat different point of view) on another
:mailing list. The 68K is much more like a PDP-11 than anything
:else, but it has a lot of clutter added.
what about the CP1600?
:That's my third of a tanner.
hey! some of us are post-decimalisation, you know!
