Cintra 911 Statistician Introduction Article
Modern Data, February 1971

This article announces the Cintra 911 Statistician calculator, which was a modification of Cintra's original calculator, the Cintra 909 Scientist calculator. The 911 involved some minor microcode changes to replace a few functions of the 909 with statistics-related functions for the 911, along with replacement of a couple key-caps with different functions listed on them. This article like post-dates that actual introduction of the Cintra 911 by a month or two, given typical magazine publication lead-times.
