NWG J. Postel, V. Cerf RFC # 174 UCLA-NMC NIC # 6799 Computer Science Categories: D.6,I.1 8 June 71 References: 134 Obsoletes: none UCLA-Computer Science Graphics Overview I. Hardware A. Imlac PDS-1 We have 2 PDS-1 graphics consoles each with 8K 16 bit words of memory. The display screens are mounted with the long axis vertical. B. DEC 340 We have a DEC 340 Display Station with a light pen. Associ- ated with the station are a Rand Tablet and a Lincoln Wand. There is a display processor which drives the DEC 340 which reads its instruction from the XDS Sigma 7 memory via dedi- cated memory port. II. Software A. Imlacs We have not as yet developed any software for the PDS-1. We have used the Imlac provided text and graphics support software to utilize the PDS-1's as alphameric and limited graphics consoles (at 1200 baud). These are used only with the SEX timesharing system. B. DEC 340 We have over several years developed a package of Library routines* which interface to FORTRAN programs for use with the DEC 340 and its associated devices. This station is used only with a stand alone system (RAD 75). Several programs have been implemented using these facilities among them are: *SMOG (sub-program manager for On-Line Graphics).
