Some of the previous responses have mentioned the CRISP machine.
I thought I'd post pointers to info:

   D. R. Ditzel, H. R. McLellan, and A. D. Berenbaum,
   "The Hardware Architecture of the CRISP Microprocessor",
   Proceedings fo the 14th Annual Symposium on Computer
   Architecture, 1987.

   Other articles releated to the CRISP machine appeared in:

      ASPLOS II, October 1987.
      COMPCON, February 1987.
      ISSCC, February 1987.

Well, there was the TI 990 microprocessor... it used main memory for
its "registers", including the PC. Of course it didn't have a cache to
speak of, so it ran like molasses, but it was still an interesting
idea.

The TI 990 was an interesting idea.  TI was apparently so impressed by the
way the hardware effort went that it put the hardware guy responsible in
charge of software as well.  Horror stories on request.
