<strong>Synergy</strong> <strong>User</strong> <strong>Manual</strong> <strong>and</strong> <strong>Tutorial</strong><br />

In 1948, at the University of Manchester in Engl<strong>and</strong>, the Small Scale Experimental<br />

Machine, nicknamed the “Baby”, successfully executed its first program, becoming<br />

world's first stored-program electronic digital computer. Frederic C. Williams (1911 -<br />

1977) <strong>and</strong> Tom Kilburn (1921 - 2001) built the machine to test the Williams-Kilburn<br />

Tube (type of memory composed of cathode vacuum tubes storing one bit of information<br />

on a cathode ray tube, illuminating a point on the screen that stays on) for speed <strong>and</strong><br />

reliability, <strong>and</strong> to demonstrate the feasibility of a stored program computer. Its success<br />

prompted the development of the Manchester Mark I, a useable computer based on the<br />

same principals. The picture shows the “Baby” (replica), the shortest cabinet at the right,<br />
