K Processor in Sun Workstation 
		    without K-based programming environment


                Hardware                       Software


     K         K Processor                    Common Lisp
					      Debugger
                                              Communications			
					      Processes/Scheduler


    Sun        Sun Processor                  Unix (+ file system, io drivers)
               Network                        Editor (gnu, unisys)
               Disk                           K Communications
               Console



   This configuration would be the quickest to develop, as it would require the
minimum of new software.  The Lisp programming environment of this
configuration would be similiar to Lucid or Franz Lisp running on a Sun
Workstation.

  The Sun would handle all IO devices including disk, network, and console.
The programming environment, including editor, window system, and any graphics
would run on the Sun.  The K would use the Sun file system and would not
require its own.

  The communications between the Sun and the K Machine would consist of a
paging protocol, a file access protocol and a text stream through a shared
memory link.  ND, TCP/IP/UDP, and NFS protocols might be appropriate here.

  Minimum documentation for this product would consist of the Common Lisp book,
Gnu Emacs manual, a hardware installation guide, and documents comparable in
scope to the Sun Common Lisp Manual (approx 100 pages) and the Sun Common Lisp
Software Installation Guide (approx 35 pages).

               Disk                           
               Console


   This configuration provides a complete Lisp machine style environment
and a Sun Unix environment within the same box.  

   The software complexity of this configuration would be decreased from that
of a stand alone K workstation by not requiring a file system and IO drivers;
but would be increased by the problem of integrating the two systems.  A
complete workstation would probably be more straightforward to develop and more
robust in use.

			    A Complete Lisp Workstation

	       Console                        (File System)
					      Processes/Scheduler
                                              Object System (CLOS, Common Loops, Flavors?)

					      Graphics
					      Mail Reader (Zmail)
					      (ZetaLisp Compatability Package)
					      Tape System / File System Editor


  This configuration provides a complete workstation similiar in scope to a
Symbolics 36xx or Lambda with much greater performance.  It provides the most
powerful and flexible Lisp development environment. 

  This configuration requires the most hardware and software.  The software
task is simplified by not requiring any integration with other vendors existing
software (except at the level of network protocols).

					      (High Level Window System (w/ network server NeWS or X))


    Sun       Workstation                     OS
    etc.                                      Communications
					      (Network Window System)


   In this configuration, the K Machine does not have a console but acts as a
network Lisp server to any user machine (such as Sun, PC or Macintosh) which
connects to it through a network. For best results, the connection would be
through a network window system.

   The software task is smaller than that for a complete workstation as many
environment features are not needed.
