The author discusses mode D control machine for industrial production. An industrial control machine is required to have a higher operating reliability than conventional general-purpose computers and can be used for production evaluation and analysis, troubleshooting, alarm signaling, and process control. Principal components are a calculator, a controller, an inner storage device, an outer magnetic drum, an input and output circuit comprising photoelectric reading devices and electric typewriters, a program input section, a program output section, and an operation control station. The program input section uses a reed type relay for sampling, a solid-state differential amplifier as the digital preamplifier, and an analog-digital converter. The program output section comprises a digital-analog converter, a servomotor, and a distributor. Technical specifications of model D control machine are number system adopted, binary type of operation, synchronous operation in parallel operating frequency, 500kc operating speed, 10,000 timessec average type of address, single address variable number of instruction codes, 64 storage capacity, 8192 characters for inner storage and 30,000 characters for outer magnetic drum.
