The IBM 7700 Data Acquisition System was introduced by IBM on December 2, 1963.
This system was capable of simultaneously gathering data from as many as 32 different sources, processing the information, and delivering output to up to 16 remote devices such as printers, display units, or plot boards.
The IBM 7700 experienced a brief period on the market before being succeeded by the IBM 1800 Data Acquisition and Control System on November 30, 1964.
Only two units of the IBM 7700 are documented to have existed: one located at the University of Rochester and another at Stanford University, both provided by IBM as donations.
Designed with an 18-bit architecture, the IBM 7700 utilized instructions composed of two 18-bit words. Arithmetic operations completed within two to three machine cycles—multiplication required approximately eight cycles, while division took twelve. Each machine cycle lasted two microseconds. Although the system’s addressable memory could accommodate up to 262,144 words, the installed memory in these machines ranged from 16,384 to 49,152 words.
Despite being introduced during the era of the IBM 7000 series, the IBM 7700 is not considered part of that particular series.
