The IBM 7700 data acquisition system was announced by IBM on December 2, 1963. [1]
She was able to collect data from 32 sources at the same time, process them and transfer the results to 16 remote printers, information display devices or storyboards.
Using the IBM 7700 was short-lived. On November 30, 1964, it was replaced by an IBM 1800 data acquisition and management system.
It is known that at least two such devices were used: one at the University of Rochester [2] [3] , and the other at Stanford University . [4] [5] Both were donated by IBM.
The IBM 7700 was an 18-bit system, with instructions spanning two 18-bit words. Arithmetic instructions were usually executed in two or three machine cycles, but, for multiplication, about 8 cycles were used, and for division 12 cycles were excluded. The machine cycle lasted two microseconds. The address space had 262144 words, but both machines were known to use 16384, 32768 or 49152 words.
The IBM 7700 was a contemporary of the IBM 7000 series , but was not considered a member.
