(a) Notes on some important events; (b) ICT computers in use at November 1966 excluding all the 1900 Series; (c) covering letter.

Each of these three items is a single A4 typed sheet but the sheets were originally stapled together. The first item, which gives dates of significance to ICT, contains some historical errors. The second item might possibly be correct but there are doubts, eg, about the number of Ferranti Mark I�s still working. The covering letter is dated 8/12/66. The three items are archived at the Science Museum Document Centre as ref. COM/1993/1446.
