AMF 665/D

This versatile, completely portable analog computer is compactly constructed and housed in a durable vinyl covered case. It may readily be carried between classroom and laboratories or taken home by students. It makes use of state-of-the art integrated circuit operational amplifiers. Because it has a self contained power supply patch cords and meter, no additional equipment need be purchased.

There are three identical summing units, which can perform addition, subtraction, and multiplication or division by constants. Each of these summing units can handle up to six input signals; two of which are automatically multiplied by ten. Additional capability for multiplying or dividing is provided by an adjustable coefficient control covering the range from 0.0 to 1.0. The analog computer also contains two identical integrator units with a settable initial condition control.

Capability for summing three input signals is provided in the integrators, and, as with the summers, one input signal is automatically multiplied by ten. A built in time base generator allows for integration continuously or in timed increments.

Simple to operate and understand, the AMF Educational Computer brings new meaning to mathematics and science for high school and college students. Originally designed to be used in "The Man-Made World" course developed by the Engineering Concepts Curriculum Project (ECCP) the computer illustrates the application of analog computing techniques to the solution of simple problems involving dynamic simulations of physical relationships. It is suitable for use in problems represented mathematically by simultaneous algebraic equations or second order differential equations.
