Despite its popularity with the students, it was deleted from the school district's mainframe computer at the end of the school semester. Rawitsch recreated the game in 1974 for the MECC, which distributed educational software for free in Minnesota and for sale elsewhere, and recalibrated the probabilities of events based on historical journals and diaries for the game's release the following year. After the rise of microcomputers in the 1970s, the MECC released several versions of the game over the next decade for the Apple II, Atari 8-bit family, and Commodore 64 computers, before redesigning it as a graphical commercial game for the Apple II under the same name in 1985.
