Computer   Automated   Measurement   And   Control(CAMAC)
          represents  a non-proprietary standard for interfacing modular
          instrumentation to digital  computer  systems.   The  standard
          specifies  electrical,  mechanical and logical characteristics
          for designing such instrumentation as well  as  specifications
          for  a  digital data bus to link these instrumentation modules
          to  the  host  computer  system.   Just  for  reference,  IEEE
          standards 583-1975, 596-1976 and 595-1976 define CAMAC.

               The software contained in this distribution represents  a
          CAMAC  system  developed  at the Oak Ridge National Laboratory
          for the Fusion Energy Division VAX  11/780  computer  systems.
          It  is  designed  around the Kinetic Systems 2050 series CAMAC
          highway driver  unit.   The  system  consists  of  four  major
          software components.

               1.  A VMS device driver supports the QIO interface to the
                   serial and/or parallel CAMAC highway interfaces.

               2.  A CAMAC Ancillary  Control  Process(ACP)  provides  a
                   support  for  LAM  management and CAMAC crate control
                   functions.

               3.  A library of CAMAC I/O procedures provides convenient
                   user  access to the functionality of the CAMAC device
                   driver and/or the ACP, insulating the user  from  the
                   details of performing direct QIO requests.

               4.  A CAMAC  Topology  Supervisor(CTS)  utility  provides
                   convenient   access   to   privileged  I/O  functions
                   performed by the CAMAC device driver and/or ACP  such
                   as  defining  logical to physical module equivalences
                   and performing crate control functions.


               The  system  distribution  consists  of   the   following
          directories.

               1.  [CAMAC.COM]

                   Contains DCL command files for performing most of the
                   maintenance  functions  associated  with the ORNL VAX
                   CAMAC system.

               2.  [CAMAC.SOURCE]

                   Contains source language, object, listing and library
                   files  associated  with  the  ORNL  VAX CAMAC system.
                   These files should all be current so that there is no
                   need to perform a new source level system generation.

               3.  [CAMAC.EXAMPLES]

                   Contains a number of  sample  programs  demonstrating
                   the use of the VAX CAMAC access procedure calls.
                                                                  Page 2


               4.  [CAMAC.DOC]

                   Contains source for RUNOFF  and  HELP  utility  files
                   describing the ORNL VAX CAMAC system.

               5.  [CAMAC.CTS]

                   Contains source, object and listing files along  with
                   the   executable   image   for   the  CAMAC  Topology
                   Supervisor(CTS) utility program.


                    Two manuals are included in the system distribution.
               One, the "ORNL VAX CAMAC System Manager's Manual" is only
               partially complete at the present time.  The  other,  the
               "ORNL  VAX  CAMAC  System  User's Guide", provides a good
               introduction  to  the  system,  explanation  of  concepts
               associated   with   the   system   design   and  examples
               demonstrating the use of the various CAMAC access calls.

                    If  you  should  decide  to  use  this  system   and
