+                 RAND/UCSB NETWORK GRAPHICS EXPERIMENT
+
+INTRODUCTION
+
+   During the Network Graphics Meeting in July, several experiments were
+   outlined to explore graphics over the Network.  One of these was the
+   use of the UCSB On-Line System (OLS) from graphic consoles at Rand.
+
+   The connection was completed in the latter half of August and has
+   been used on an experimental basis since then.  OLS users from UCSB
+   and TRW (in Los Angeles) have visited Rand and accessed OLS via Rand
+   consoles and the Network.  Thus, the first phase of the experiment
+   was completed in August.
+
+   We are still in the midst of the second phase of the experiment which
+   involves cleaning up the initial implementation and reviewing and
+   modifying our initial strategies for the OLS connection.
+
+IMPLEMENTATION OF THE EXPERIMENT
+
+UCSB
+
+   UCSB has had a Network interface on the OLS for some time.  For a
+   description, see RFC #74.  The descriptions in RFC #74 were modified
+   to conform to current Network protocols (NCP and ICP) and to conform
+   to what we considered a general graphics description.
+
+   Basically, the OLS receives an EBCDIC-like input byte stream and
+   generates an unstructured graphical output stream.  These protocols
+   will be documented at the completion of our experimentation and
+   presented at the Network graphics meeting in October.
+
+   The Rand Video-Graphics System (VGS) was used to access the OLS via
+   the Network.  The Video-Graphics System and its consoles are
+   described in R-753-ARPA available from the Rand Reports Department.
+
+   VGS consoles had been connected previously to the Network via the
+   Rand Network Services Program (NSP).  Originally, NSP was designed to
+   afford NCP checkout features, logging in to and use of remote systems
+   and access to UCSB RJE and UCLA RJS.  An additional module was easily
+   added to access the OLS.

+RFC 225          RAND/UCSB NETWORK GRAPHICS EXPERIMENT    September 1971
+
+
+   Input to the OLS was done via a Rand tablet on a VGS console.  Input
+   to the OLS module in NSP is accomplished by moving the tablet cursor
+   (not shown in the attached figures) which appears as a small dot on
+   the screen to the desired function button and pressing the tablet pen
+   down on the tablet.
+
+   Figure 1 shows the initial display from the OLS module.  The top of
+   the screen has a feedback line, the remainder of the upper half is
+   the output display from the OLS, and the lower half is a large
+   sensitive area containing various function buttons (pic-table).
+
+   The sensitive areas fall into three classes:
+
+          (1)  the right most column (CALL, CLOSE)
+          connects/disconnects to OLS over the Network.
+          The third function (COPY) generates hardcopy
+          via an SC 4060. (The figures are, in fact,
+          SC 4060 hardcopy.)
+
+          (2)  The grid area contains the OLS function
+          buttons normally on a special function keyboard.
+          (See RFC #74.)
+
+          (3)  The lower area allows entry of number,
+          characters and punctuation.
+
+   Figure 2 shows the login sequence to OLS and Figure 3, SIN and COS
+   curves from -PI to +PI generated by OLS.
+
+   Completion of the Experiment
+
+   We plan to present the experiment at the October graphics meeting in
+   two forms.  First, a description of the protocols and techniques used
+   in implementing the remote network connection along with conclusions.
+   Second, we will make a film showing the use of the OLS from Rand and
+   present it at the meeting.
