IBM 1800
From Wikipedia, the free encyclopedia
The IBM 1800 was a process control variant of the IBM 1130 with two extra instructions (CMP and DCM) and extra I/O capabilities. Unlike the 1130, which was a desk-like unit, the 1800 is packaged in typical IBM racks. As of February 2006 4 IBM 1800s were still in operation at the Pickering Nuclear Generating Station in Pickering, Ontario, Canada.
