At present, users with TEKTRONIX or IMLAC terminals or with systems
that support the proposed level 0 graphics protocol can access UCSB
graphics.  Listed below are the ICP sockets for the currently
supported terminals and protocols.  Any detailed questions about or
problems with a particular protocol should be directed to Ed Faeh
(805-961-4047).

   Socket                       Supports

   x'701'               IMLAC with special software designed
                        by Jerry Powell (MITRE Corp.).
                        Graphics is sent over a simplex
                        connection to the IMLAC.  Alphanumerics
                        are sent over a TELNET-like connection
                        to a separate device.  The IMLAC
                        software can be loaded from MIT-DMCG.

   x'703'               IMLAC with 80x80 display grid
                        and Standard Text and Edit Package.
                        Some IMLACs have a 64x64 display grid.
                        Therefore, the choice may be made in
                        the near future to format the
                        graphics output from this connection
                        for the smaller grid resolution so
                        that both terminal types may be handled.
                        Display resolution is limited with
                        this terminal configuration as
                        normal UCSB terminals have 1024x1024
                        grid.  Nevertheless, meaningful
                        displays are obtained even at the
                        lower resolutions.

   x'705'               Current Level 0 graphics protocol.

   x'707'               Same as x'701' but with special
                        UCSB online keyboard as input.
                        This configuration averts the
                        necessity of spelling out online
                        operators.

   x'709'               Same as x'705' but with special
                        UCSB online keyboard as input.
