   :The PDP-11 architecture has only 7 GP registers (since you can't

   :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?

hey! some of us are post-decimalisation, you know!
