IBM 1130
The IBM 1130 Computing System was introduced in 1965. It was IBM's least-expensive computer to date, and was aimed at price-sensitive, computing-intensive technical markets like education and engineering. It succeeded the IBM 1620 in that market segment. The IBM 1800 was a process control variant...

 with two extra instructions (CMP and DCM), extra I/O capabilities, 'selector channel like' cycle-stealing capability and three hardware index registers.

IBM announced and introduced the 1800 Data Acquisition and Control System on November 30, 1964, describing it as "a computer that can monitor an assembly line, control a steel-making process or analyze the precise status of a missile during test firing.".

Unlike the 1130, which was a desk-like unit, the 1800 is packaged in 6 foot high, EIA Standard 19 inch racks, which are somewhat taller than the racks used by S/360 systems of the same vintage, but the internal gates and power supplies were very much the same. Many 1800 cabinets show a distinct "ding" on the vents at the top of the chassis, where movers discovered that the door into a computer room was not quite tall enough for the 1800 cabinet.

General

The IBM 1800 DACS consisted of:
  • D/A (Digital-to-Analog) Converter
  • A/D (Analog-to-Digital) Converter
  • IBM 1801 Processor Controller, with operator's panel
  • IBM 1802 Processor Controller, with operator's panel, to include adapters for 2401/2402 Magnetic Tape Units.
  • IBM 1803 Core Storage Addition
  • IBM 1826 I/O Expansion Chassis (used for communications I/O, System/360 channels, 279x)
  • IBM 1828 Process Expansion Unit (used for additional D/A or A/D converters, or to hold 1851 and/or 1854 multiplexors; there was an RPQ for a remote 1828 unit)
  • IBM 1810 Disk (equivalent to 2310 on IBM 1130)
  • IBM 1816 Printer Keyboard (System Printer)
  • IBM 1851 Reed Relay Analog Multiplexor
  • IBM 1854 Solid State Analog Mulitplexor
  • IBM 1894 generic model number for many 1800 RPQ hardware features, which inter alia, included support for IBM 109x data entry devices)
  • IBM 1053 Printer
  • IBM 1054 Paper Tape Reader Unit
  • IBM 1055 Paper Tape Punch Unit
  • IBM 1442
    IBM 1442
    IBM 1442 was a combination IBM card reader and card punch. It read and punched 80-column IBM-format punched cards and was used on the IBM 1440, the IBM 1130, the IBM 1800 and System/360 and was an option on the IBM System/3. The 1442 could read up to 400 cards per minute. Cards were read and...

    The IBM 1627 was a rebranded Calcomp plotter sold by IBM for use with the IBM 1620, and, later, the IBM 1130 computers. It became perhaps the first non-IBM peripheral that IBM allowed to be attached to one of its computers....

  • IBM 2401 or 2402 Magnetic Tape Unit (its adapter included in IBM 1802)
  • IBM 2311 DASD (attached via an IBM 2841 Control Unit, latter attached to a channel in the IBM 1826), the MPX operating system could map two 1810 disks per 2311, the 1810 drive mapping being seen as a DSCB Form 5 dataset to S/360 OS)
  • IBM 2260

    The text-only 960-character monochrome IBM 2260 cathode ray tube video display terminal plus computer keyboard was a 1964 predecessor to the more-powerful color text-and-graphics IBM 3270. The 2260 screen image was normally configured with 12 lines of 80 characters each, which corresponded to IBM...
