The IBM 7700 Data Acquisition System was announced by
IBM on December 2, 1963.
It is 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
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 reg ...

The IBM 7700 is an 18-bit system, with instructions occupying two 18-bit words. Arithmetic instructions generally execute in two or three machine cycles, except for multiply, about 8 cycles, and divide, 12 cycles. A machine cycle is two microseconds. 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.

is 262,144 words, but the two machines known to have been built had 16,384, 32,768 or 49,152 words.
The IBM 7700 is contemporary with the IBM 7000 series but not considered a member of it.
