HC Deb 15 June 1965 vol 714 c53W
Mr. Walder

asked the Chancellor of the Exchequer whether he will list those computers operating in Government establishments which are regularly manned 24 hours a day in order to provide a full operational service.

Mr. Callaghan

One computer is expected to come into operation on a 24-hour basis within the next few months. Normal working is up to 15 hours per day.
