IBM Personal Computer Graphical Kernel System 1.00

IBM Personal Computer Graphical Kernel System is a standardized graphics interface programming library designed to simplify portable software development across IBM's different video card. It provides bindings for languages, including BASIC, C, and FORTRAN. It was primarily designed for use with the IBM Professional Graphics Adapter.

Several additional development packages were designed to use under the GKS package. These include:
