Description
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.
Groups of the punch cards are not numbered but some are grouped by black marks on the edge. The cards have the data for a FORTRAN program with non-accession number 1990.3046.10. The cards are white with a pink, green or no border on the top. A mark on the first card reads: 8258, CLAF6, D7300, 04M, 100CD, 150P, C.
