Hitachi Analog Hybrid Computer HITACHI-200X
Sales brochure for the Hitachi-200X analog hybrid computer, describing a desk-top or rack-mounted machine designed so that the operator patches a block diagram directly on the patch board without requiring knowledge of electronic circuit terms. The brochure covers key innovations including direct block-diagram programming, three ranges of coefficient potentiometers (0.1, 1, 10), a Program Check System (PCS), dual-point shielded patch contacts, IC-based operational amplifiers, and digital coefficient amplifiers for hybrid operation. General and individual specifications are tabulated, application examples spanning linear and nonlinear differential equations, epidemiology, germs-in-water problems, earthquake response, and industrial simulation are illustrated, and a full composition table lists available computing element configurations (A-10, A-20, 2S, 2LS, 3, 3S, 4, 4S, 4LS).
