Harslem Rand +Request for Comments: 225 UCSB +NIC 7624 13 September 1971 +Category: D.6 +Updates: RFC #74 + + + 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. + + + +Stoughton [Page 1] + +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. + + + + + + + + + + + + + + + +Stoughton [Page 2] + +RFC 225 RAND/UCSB NETWORK GRAPHICS EXPERIMENT September 1971 + + ++--------------------------------------------------------------+ +| | +| | +| |-+ +| UCSB OLS INIT STATS | |Feed- +| |-+back +| |-+ +| | | +| | | +| | | +| | | +| | | +| | | +| | | +| | | +| | |OLS +| | |Dis- +| | |play +| | |Area +| | | +| | | +| | | +| | | +| | | +| | | +| | | +| | | +| |-+ + +---+---+---+---+---+---+---+---+---+---+---+---+---+---+ |-+ +|| 0 | I | II|III|IV | V |VI |VII|REL|CMX|SYS|USR|TYP|LST|CALL | | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | | +||PLS|MIN|TIM|DIV|SQ |SQT|CNJ|INV|DIF|SUM|PRD|SOR|PRD|TST|CLOSE| | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | |Input +||LS |RS |REF|UP |DWN|EVL|SUB|MAX|MOD|NEG|CTX|ENL|CON|RPT|COPY | |But- +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | |tons +||SIN|COS|LOG|EXP|PWR|ATN|ARG|DEL|CNV|ID |LOD|STO|ENT| | | | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | | +||CAS| | | | | | |DIS|<<<|BEL| |ERS|RST| | | | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | | +| ABCDEFG + = / # 12345 | | +| HIJKLMN , ; = . 67890 | | +| OPQRSTU <-<-<-<- ()? | | +| VWXYZ b ' \ \ |-+ ++--------------------------------------------------------------+ + + + + + + + +Stoughton [Page 3] + +RFC 225 RAND/UCSB NETWORK GRAPHICS EXPERIMENT September 1971 + + ++--------------------------------------------------------------+ +| | +| | +| |-+ +| UCSB OLS CONNECTED | |Feed- +| |-+back +| ENTER USER NUMBER 196 |-+ +| ID NUMBER= | | +| USER NAME= ARPA | | +| JOB NAME= RAND/RFC | | +| AUTOSAVE CODE = 3 | | +| LOAD MOLSF | | +| FILE LOADED | | +| | | +| | | +| | |OLS +| | |Dis- +| | |play +| | |Area +| | | +| | | +| | | +| | | +| | | +| | | +| | | +| | | +| |-+ +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ |-+ +|| 0 | I | II|III|IV | V |VI |VII|REL|CMX|SYS|USR|TYP|LST|CALL | | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | | +||PLS|MIN|TIM|DIV|SQ |SQT|CNJ|INV|DIF|SUM|PRD|SOR|PRD|TST|CLOSE| | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | |Input +||LS |RS |REF|UP |DWN|EVL|SUB|MAX|MOD|NEG|CTX|ENL|CON|RPT|COPY | |But- +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | |tons +||SIN|COS|LOG|EXP|PWR|ATN|ARG|DEL|CNV|ID |LOD|STO|ENT| | | | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | | +||CAS| | | | | | |DIS|<<<|BEL| |ERS|RST| | | | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | | +| ABCDEFG + = / # 12345 | | +| HIJKLMN , ; = . 67890 | | +| OPQRSTU <-<-<-<- ()? | | +| VWXYZ b ' \ \ |-+ ++--------------------------------------------------------------+ + + + + + + + +Stoughton [Page 4] + +RFC 225 RAND/UCSB NETWORK GRAPHICS EXPERIMENT September 1971 + + ++--------------------------------------------------------------+ +| | +| ___ ___ |-+ +| / \ / \ | | +| / \ / \ | | +| / \ / \ | | +| / \/ \ | | +| / /\ \ | | +| / / | | +| / \ \ | | +| / \ \ | | +| / / | | +| \ \ | | +| / / \ \ | | +| ___________________________________________ | | +| | | +| \ | | \ | |OLS +| / / | |Dis- +| \ \ | |play +| / / | |Area +| \ / \ | | +| / \ | | +| \ / / | | +| \/ / \ | | +| \ / \ | | +| / \ / \ | | +| / \ / \ | | +| __/ \___/ \__ | | +| |-+ +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ |-+ +|| 0 | I | II|III|IV | V |VI |VII|REL|CMX|SYS|USR|TYP|LST|CALL | | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | | +||PLS|MIN|TIM|DIV|SQ |SQT|CNJ|INV|DIF|SUM|PRD|SOR|PRD|TST|CLOSE| | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | |Input +||LS |RS |REF|UP |DWN|EVL|SUB|MAX|MOD|NEG|CTX|ENL|CON|RPT|COPY | |But- +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | |tons +||SIN|COS|LOG|EXP|PWR|ATN|ARG|DEL|CNV|ID |LOD|STO|ENT| | | | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | | +||CAS| | | | | | |DIS|<<<|BEL| |ERS|RST| | | | +|+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | | +| ABCDEFG + = / # 12345 | | +| HIJKLMN , ; = . 67890 | | +| OPQRSTU <-<-<-<- ()? | | +| VWXYZ b ' \ \ |-+ ++--------------------------------------------------------------+ + + [ This RFC was put into machine readable form for entry ] + [ into the online RFC archives by Mark Davidson 1/00 ] + + + +Stoughton [Page 5] + |
