- 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.
- This group of cards is labeled: Last version using SC4020 plot routine. The cards have the data for a FORTRAN program with non-accession number 1990.3046.10. Theys are white with a green border along the top. A mark on the first card reads: $IBFTC CLAQR REF.
- The SC4020 was a computer-controlled microfilm printer and plotter produced by the Stromberg-Carlson Corporation. It was one of the first devices sold specifically to visualize computer calculations.
