Scope and Content

Experiments conducted by Eric Sunderland in the period Sept. 1969 to August 1970. Buff foolscap folder containing:

(a) code of a program to modify the Supervisor so that page-usage information is preserved to disc;
(b) several sample line printer outputs of the statistics;
(c) two double-foolscap sheets of squared paper on which Eric Sunderland has transcribed many results. These experiments were carried out for Frank Sumner, who at the time had a Ph.D. student studying paging behaviour.
