SR-52 Calculator - 1976
TI number: S00297

This item is a prototype SR-52 hand held magnetic card programmable calculator in a clear plastic case. IC date codes indicate this calculator probably was built in January or February, 1976.

To check the case design and molds, an initial case was molded in clear plastic and assembled with the calculator assembly. Points of interference of misalignment could then be identified and corrected. A few clear cases were also often used to display the calculators. The SR-52 was introduced in September, 1975, with a price of $395.00. A copy of the press release announcing the calculator and its capabilities is in the Artifacts Historical File.
