The CARDboard Illus-trative Aid to Computation — calledCARDIAC, for short — is a cardboardmodel which has the basic workingparts of an actual digital computer. It was designed by David W. Hagei-barger, a member of the InformationProcessing Research Departmentat. Bell Laboratories, for use in The Man-Made World, a new program de-signed to improve the teaching of highschool science. With the aid of CARDIAC, studentsare becoming aware of the computer,not as a thinking machine, but as amachine responsive to mans instruc-tions. By following a red line path onthe plastic and cardboard model, stu-dents can follow steps taken by a com-puter in executing programs and canuse CARDIAC to solve problems. Theycan perform logical operations and seehow abstract concepts of logic can bemade concrete in circuits similar tothose used in computers. Thus, the cardboard computer givesthe student a working illustration ofprinciples discussed in Logic andComputers, the first phase of the ex-perimental course which was preparedby contributors to the EngineeringConcepts Curriculum Project. Five BellLabs engineers and scientists, profes-sors from a number of universities,and several high school science teach-ers are among those contributing tothe
