             THE CAMBRIDGE UNIVERSITY EDSAC
             ------------------------------
EDSAC, Electronic Delay Storage Automatic Computer, was built by
Maurice Wilkes and colleagues at the University of Cambridge
Mathematics Lab, and came into use in May 1949. It was a very well-
engineered machine, and Wilkes designed it to be a productive tool
for mathematicians from the start. It used mercury delay line
tanks for main store (512 words of 36 bits) and half megacycle/S
serial bit rate. Input and output on paper tape, easy program
load, nice rememberable machine order-code. See Resurrection
issue 2 for some of Wilkes' design decisions.

Simulators of EDSAC included here are:

There are excellent simulators by Martin Cambell-Kelly for the
PC (running under Windows 95 or NT), and for the Macintosh. These
come with many example programs. Point your browser to:
