content: In the mid-1960s, the Computer Science Department at RAND Corporation turned its attention to developing computer graphics. A set of programs written in the programming language FORTRAN for the PDP-9 minicomputer were used to plot contour lines useful in determining the line of sight for microwave radiation emitted from a given point on a map. These cards have some of the data for one of these programs. The cards are white with a pink border on the top (occasional cards have a green border). Groups of cards are not numbered but groups of data are designated by black marks on the edge. A mark on the first card reads: 3000 500. A printout of a related program has non-accession number 1990.3046.10.
