Adler EC 60 Handheld Electronic Calculator

This relatively large handheld electronic calculator has an array of ten digit keys on the front, and four colored keys for division, multiplication, subtraction and addition along the right front. To the left of the zero key is a clear key, to the right a decimal point key. Behind the keys is a six-digit blue-green fluorescent display. Behind this is space for four 1.5 volt batteries. There also is a plug for a power adapter.

A mark on the front behind the display reads: ADLER 60. Stamped on the bottom of the plastic case are instructions for a typical calculation. A tag attached there reads: T-A Vertriebs-GMBH. 85 Nürnberg (/) Type EC 60 (4x1.5V-Dry Batteries or (/) AC Adapter AD 10.11.12.13.14.15.16 (/) Made in Japan No. 65053135.
