Hitachi 505E Analog/Hybrid Computer
Sales brochure for the Hitachi 505E analog/hybrid computer, a desk-top all-solid-state machine expandable from 10 to 124 operational amplifiers across four standard configurations (505-10, 505-30, 505-60, 505-120). The brochure details outstanding features including 100V operational amplifiers, three-cycle high-speed repetitive operation, color-coded shielded patch panel, servo-set potentiometers, built-in four-channel oscilloscope, and an integrated digital logic package with flip-flops, AND gates, counters, comparators, and mode-matrix for full hybrid computation. Component descriptions cover dual and quad amplifiers (DA-151A, DA-153), RMC and EMC integrator networks, electronic multipliers (EM-151, EM-153), variable and fixed diode function generators, relay comparators, time delay units, and a trunk unit for external digital computer interfacing.
