Punch Cards Used with a PDP-9 Minicomputer


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.

Groups of cards are numbered from 31 through 45. The program has non-accession number 1990.3046.10. A mark on the top card reads: DATE GENERATED 4-11-68.
