This issue features two important aspects of history of computing: computers in education and microcircuitry. Specifically, the issue includes features on the development of Watfor, a fast student-oriented Fortran compiler, at the University of Waterloo; a history of time-shared microcomputers in the early 1980s; a history of educational computers in Australia; Geoffrey W.A. Dummer´s semiconductor innovation at the British Royal Radar Establishment in the 1950s; and Jay W. Lathrop´s description of developing the photolithographic approach to microcircuits at the US Army Diamond Ordnance Fuze Laboratory.
