EAI MiniAC analog computer with EAI Repetitive Operation Display Unit (RPI 0314) and EAI Variplotter 1110 plotter unit: the MiniAC measures 32.5 x 22 x 13, the Repetitive Operation Display Unit with bright orange oscilloscope face (model 34.035) measures 11.5 x 7.75 x 20.75, and the Variplotter measures 19 x 21 x 8.5. The MiniAC was introduced by Electronic Associates, Inc. as a small tabletop transistorized analog computer, designed for students and researchers to run small models and simulations. The front has a colorful patchboard interface with numerous knobs, switches, and buttons. Untested and in overall very good to fine cosmetic condition, with scuffing to the surface of the plotter and a broken strap to the oscilloscope machine.
