Cambridge (I-40) Calculator

This is a Calculator. It is dated 1973 and we acquired it in 2008. Its medium is plastic. It is a part of the Product Design and Decorative Arts department.

The Cambridge model calculator was available in a total of 12 iterations, ranging from a simple four-function version to a programmable device. Most versions, such as the one proposed for acquisition, use AAA pen cell batteries to maintain their slim profile.
The museum actively collects in the area of personal electronic devices. This calculator is part of a group of electronics proposed for acquisition that would augment the collection’s consumer product design category.

This object was donated by Max Pine. It is credited Gift of Max Pine and Lois Mander.

Its dimensions are

H x W x D: 5.1 x 11.2 x 2.8 cm (2 x 4 3/8 x 1 1/8 in.)
