IBM 7700 Data Acquisition System
Encyclopedia
The IBM 7700 Data Acquisition System was announced by IBM on December 2, 1963.
It was capable of collecting data from as many as 32 sources simultaneously, process the data and transmit results to up to 16 remote printers, display units or plot boards.
The IBM 7700 was short-lived, being replaced by the IBM 1800 Data Acquisition and Control System on November 30, 1964.
Two IBM 7700 Data Acquisition
Systems are known to have existed: one at the University of Rochester
and the other at Stanford University
. Both were donated by IBM.
The IBM 7700 was an 18-bit system, with instructions occupying two 18-bit words. Arithmetic instructions generally executed in two or three machine cycles, except for multiply, about 8 cycles, and divide, 12 cycles. A machine cycle was two microseconds. Address space
was words, but the two machines known to have been built had , or words.
The IBM 7700 was contemporary with the IBM 7000 series but not considered a member of it.

Data acquisition
Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems typically convert analog waveforms into digital values for processing...

Address space
In computing, an address space defines a range of discrete addresses, each of which may correspond to a network host, peripheral device, disk sector, a memory cell or other logical or physical entity.- Overview :...
