A way of introducing children to using electronic calculators was for the calculator to have an attractive casing featuring Mickey Mouse, a convenient carrying handle, and just the basic four functions.

Alco Mickey Math calculator circuit board

The simple small circuit board takes up little room inside the casing.  It holds the VFD tube showing its six digits, and the OMRON HD3639 calculator integrated circuit, together with a few capacitors, diodes, and resistors.

Other electronic calculators that were attractive to young children were subsequently marketed.
