HC Deb 03 April 1984 vol 57 c462W
Mr. Wainwright

asked the Secretary of State for the Environment how long is the currently estimated effective life of main frame computers in his Department.

Mr. Patrick Jenkin

The expected life of main frame computers in the Department of the Environment is, following standard Government contract terms, 10 years. However, technical advances sometimes make it cost effective to replace this equipment earlier.
