}}The '''IBM 1800 Data Acquisition and Control System''' (DACS) was a [[process control]] variant of the [[IBM 1130]] with two extra instructions (CMP and DCM), extra I/O capabilities, 'selector channel like' cycle-stealing capability and three hardware index registers.<ref>{{cite web |url=http://www.ieeeghn.org/wiki/index.php/IBM_1800 |title=IBM 1800 |author=Steve Wixon |date= |work=IEEE Global History Network |publisher=IEEE |accessdate=16 December 2011}}</ref>

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."<ref>[https://web.archive.org/web/20080605160205/http://www-03.ibm.com/ibm/history/exhibits/vintage/vintage_4506VV4022.html "IBM 1800 data acquisition and control system"] - IBM Corporation website - Vintage Computers section.</ref>
