                     MIL-STD-1750B -- THE FUTURE
                     ---------------------------

     Work is underway on creating a MIL-STD-1750B document.   The
purpose of  this document  would be  to clarify  and improve  the
Sixteen    Bit    Computer    Instruction    Set     Architecture
(MIL-STD-1750A),  by  including  the  suggested  improvements  of
computer manufacturers and  designers.  Changes will  be made  to
accommodate programming in the Ada programming language.

        The publication of the  MIL-STD-1750A CHANGE NOTICE 1  in
1982 resulted in a three  year freeze, imposed by the  Designated
Control Agent, on all changes  to MIL-STD-1750A.  The freeze  was
imposed to  allow computer  manufacturers to  design products  to
meet  stable   requirements.    As  computers   were   developed,
manufacturers suggested  clarifications and  improvements to  the
standard.   These  suggestions  will  be  incorporated  into  the
MIL-STD-1750B, the succeeding version to MIL-STD-1750A.

     The Society  of  Automotive  Engineers,  Aerospace  Avionics
Equipment and Integration Committee, Users Group SAE-AE-9E, is in
the process of developing a draft MIL-STD-1750B, in  anticipation
of a lifting of the freeze.  The Users Group SAE-AE-9E is working
towards achieving the following schedule:

          Fall 1985        Complete Draft
        Spring 1986        Standards Subtask Group Review
        Summer 1986        SAE-AE-9E Committee Review
          Fall 1986        Presentation to MIL-STD-1750 Control Board

     LSI LOGIC CORPORATION AND ACT CORPORATION ANNOUNCE PLANS TO JOINTLY 

             DEVELOP A 1750 BASED DESIGN AND DEVELOPMENT SYSTEM

      -------------------------------------------------------------------

  October 28, 1986  -  LSI Logic Corporation and Advanced
Computer Techniques Corporation (ACT) today announced their
intention to jointly develop and marketa n integrated
software/hardware development system for the MIL-STD-1750
microprocessor environment.  

  LSI Logic, a designer and manufacturer of HCMOS
application-specific integrated circuits (ASICs), recently
introduced the industry's first ASIC single-chip HCMOS version of
the MIL-STD-1750 microprocessor.  This cell-based custom designed
microprocessor is geared for avionics, navigational equipment,
satellites, and other military applications.  New York City based
ACT, a supplier of 1750 compilers and related support software,
was the first United States company to develop a validated Ada
compiler for the 1750.
