= EMR Computer = EMR (Electro-Mechanical Research) Computer was a wholly owned subsidiary of Schlumberger based at 8001 Bloomington Freeway, Minneapolis, Minn. 55420 The ASI Computer Division was formerly named Advanced Scientific Instruments, a subsidiary of EMR. EMR was sold to Sperry Univac on December 1, 1972 under an agreement between Sperry Rand and Schlumberger Ltd. and acquired the maintenance and lease contracts, complete factory and field inventory, all documentation for reproduction of hardware and software and all patents, trademarks and licenses.

There were over 100 Series 60 systems installed in the U.S. and over 50 in Europe. The chief applications for Series 60 systems were geophysical data processing, lab automation and communication systems, law enforcement and specialized production control systems. Geophysical data processing was also a primary application in Europe.

There were several different computer systems. The 6000 Series systems were 24 bit with a maximum of 32k words and included the 6020, 6040, 6050, 6070 and 6080. The 6020 and 6040 systems were introduced in October, 1964. The 6070 system consisted of a 6050 with the addition of an added Accelerated-Processing Unit which permits simultaneous operations independent of the main processor and commonly referred to in the field as the "Convolver". It was primarily used in seismic data processing. The ADVANCE 6080 offered features as memory protect and dynamic hardware relocation which permitted time-shared and multi-programming operations as well as multiple remote stations. The 6050, 6070 and 6080 employed the most recent developments in integrated monolithic circuitry.

The 6100 Series Systems started with the 6130, 6140, 6145 and were 16 bit systems, some with core memory expandable to 128k and optional floating point hardware. The 6130 system was first introduced in April 20, 1966 incorporating total monolithic integrated circuitry, designed for data acquisition systems and other industrial applications. Up to six fully buffered I/O channels, including word/byte channels and multiplex channels, were available. One of the most significant features of this system was its bus organization, providing for simultaneous communication and control of multiple central processors, multiple I/O channels, and multiple memory modules. Together with the new system, the ASI Computer Division provided a comprehensive software system including batch processing operating system, extended assembler, FORTRAN, and a real-time executive.

All processing systems were available with a full line of peripherals that included printers, card readers, card punches, tape drive systems, disk drives and on-line communication systems.

Sperry Univac referred all EMR systems as the "Series 60" line of computers.
