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).
