The Sumerian Game © 1966 Leonard, Jimmer.
Portage and update of the original IBM 7090 game (1964).
Following the creation of the second version of The Sumerian Game, the first segment of the game was reprogrammed by Jimmer Leonard, a graduate student in Social Relations at Johns Hopkins University, for the IBM 1401, to be used at demonstrations at a terminal in the BOCES Research Center in Yorktown Heights, New York. The project was mentioned in Time and Life magazines in 1966.
