SCM Marchant Cogito 240-SR Electronic Calculator Introductory Advertisement


Sincere thanks to Serge Devidts for providing a high-quality scan of this original advertisement to the Old Calculator Museum

This is an early introductor advertisement for the SCM Cogito 240-SR calculator. The Cogito 240SR was an updated version of SCM Marchant's first electronic calculator, the SCM Cogito 240. The 240-SR added semi-automatic square root, and additional accumulative functions with the 240-SR, but otherwise, this machine was very similar to the 240. The Cogito 240-SR was introduced in the early part of 1966.
