Electronic Circuit Analysis by Tatum Labs is a program for microcomputers which is intended to provide an alternative to breadboarding and extensive measurements. The circuit being analyzed can be tweaked on the computer without actually building it, with a very high degree of accuracy. All circuits are built from passive components (resistors, capacitors, inductors) and active components (voltage and current sources, controlled and fixed). Models of other devices such as transistors, op-amps, and vacuum tubes can be built using the components available. ECA analyzes filters, audio amplifiers, equalizers, antenna couplers, and many other analog circuits. ECA contains a chaining facility so multiple runs can be done without operator intervention, with full editing and error trapping routines. Can analyze circuits of up to 64 nodes and 127 branches. Also performs worst case analysis for finding production extremes of performance.\n\nOriginal retail price: $150/$25 (Westico Professional CP/M Software Catalog for ADAM, 1984)
