Black and white photo of the IBM 4979 on a table. On the screen is a list and execution. Back says "79-3-33-4".The language of the sample program shown is Waterloo BASIC. This can be identified by the language extensions (while/endloop, indentation, message numbering like "EX-00"). Given the date as 1979 and the IBM terminal, this terminal was connected to an IBM Series/1 minicomputer, which was the original platform on which Waterloo BASIC was implemented.
