Pickens +UCSB Online Graphics Edward D. Faeh +NIC 11911 UCSB + 22 Sept 72 + +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. + + + + + [Page 1] + +NWG/RFC# 398 JRP EDF 22-SEP-72 16:25 11911 +UCSB OnLine Graphics + + + x'801' TEKTRONIX terminals. Models 4002-A + 4010, and T-4002 have been tested + successfully. Presumably all other + 4002 compatible terminals will also work. + +The primary problems that will be encountered by the network user +center about display formatting. For historical reasons (i.e. only +one type of terminal in house ) no means were included in the system +to facilitate terminal independent random positioning of alphanumeric +output. Thus, a program which draws and labels a graph neatly on one +terminal might label like a kindergartener on other terminals. +Nevertheless, this problem can be minimized with careful programming +and efforts are underway to provide at least minimal alphanumeric +device independence. + +Users interested in experimenting with online graphics should contact +John Pickens (805-961-3454), Glen Davis (805-961-2462), or Mark +Krilonovich (805-961-3454). Suggestions and criticisms of all aspects +of the UCSB OnLine - Network User interface are desired. + + + + + + + [ This RFC was put into machine readable form for entry ] + [ into the online RFC archives by BBN Corp. under the ] + [ direction of Alex McKenzie. 1/97 ] + + + + + + + + + + + + + + + + + + + + [Page 2] + |
