Interactive graphical terminals

Two other computer facilities are a data collection system which monitors remotely located data acquisition and experiment-control computers via asynchronous serial lines and the two Evans and Sutherland LDS-1 interactive graphics terminals. A PDP 10 included in the network configuration as an alternate file transport concentrator and auxiliary network development machine also performs the role of worker computer with the Evans and Sutherland display equipment. Other subnetworks have been designed for inclusion in the Octopus network to direct the on-line operation of LLL high-speed printer and microfilm recorder output facilities, to administer a second, expanded television monitor system providing 256 channels of video input for distribution to 512 additional monitors, and to control a CDC on-line tape library of 8.7 x 10 bits scheduled for delivery in 1975. The Computer Hardcopy Output Recording System (CHORS) concentrators are two Modcomp II computers, and TMDS-II will utilize two PDP 11/45s both subnetworks are to become operational during the... [Pg.292]

Previously we reported the refinement of the structure of the RC from the R-26 strain using the Hendrickson and Konnert restrained least-squares refinement (9). Refinement cycles were alternated with model building using an interactive graphics terminal and the program FRODO (10). This yielded a R factor of 24.0% (1,3). [Pg.63]

The BIOGRAF program was run on a Micro VAX II conmuter equipped with an Evans and Sutherland PS390 graphics terminal. The size of coal structures evaluated, and the duration of molecular dynamics runs, were limited by the available computing speed of this system (a 5000-step, 10-ps molecular dynamics run for a 1040-atom structure, with about 75,000 van der Waals interactions per step, required about 100 hours of computation). [Pg.161]

Tektronix equipment, and functioning for any terminal that has 4010 emulation. The cost of this system can run from as low as a few thousand dollars for some minimal capability to thirty thousand for a full blown software system. The features of this package include software libraries as well as interactive graphics and drawing routines. [Pg.81]

In addition MOLY contains a large number of utility programs which allow for efficient molecular storage, retrieval, orientation and display. The system is written entirely in FORTRAN and executes on an IBM 370/158 under the MVS operating system and the TSO time-sharing system. User interaction is via a Tektronix 4006 or 4010 graphics terminal. Hard copy capabilities are provided via Tektronix photocopiers as well as a Calcomp digital plotter. [Pg.378]

Figure 45 shows that a rotation of the coordinate axes may improve variable by variable plots significantly. This method is very useful if an. interactive computer graphics terminal is available and if the dimensionality of the pattern space is not too large. A multidimensional rotation can be considered as a series of d(d-1)/2 two-dimensional rotations -... [Pg.98]

CADD, a part of CAD, is the computer-assisted generation of working drawings and other documents. The CADD user generates graphics by interactive communication with the computer. The graphics are displayed on a video terminal and can be converted into hard copy by a printer or plotter. [Pg.29]
