'The Post Office research workers, in their new site at Martlesham Heath, Suffolk, will be opening their computer in 1972-2 with 100 terminals attached to a central processor some three times as powerful as Atlas'.
So starts the front page lead story in Electronics Weekly's edition of July 2nd 1969.
Atlas did not have a clock, and its performance parameters were measured: fixed point B-addition: 1.59 microseconds; floating point add, no modification: 1.61 microseconds; floating point add, double modify: 2.61 microseconds; floating point multiply, double modify: 4.97 microseconds.
'About six years later the central processor will need to be 12 times the power of Atlas and will have around 400 terminals in use.', adds the EW story.
