Abstract
A programmable electronic calculator includes two cassette tape recorders as peripheral system. An optional program or a data processed by the programmable electronic calculator is introduced into and recorded on a first cassette tape recorder. The first cassette tape recorder reproduces the optional program recorded therein upon request from the programmable electronic calculator. A second cassette tape recorder carries an audible message for operation guidance purposes. An interface circuit is provided in the programmable electronic calculator for independently controlling the operation of the first and second cassette tape recorders.
