  • The Making of the MCM/70 Microcomputer
    The Making of the MCM/70 Microcomputer Zbigniew Stachniak York University, Canada MCM/70, manufactured by Micro Computer Machines (MCM), was a small desktop microcomputer designed to provide the APL programming language environment for business, scientific, and educational use. MCM was among the first companies to fully recognize and act upon microprocessor technology’s immense potential for developing a new generation of cost-effective computing systems. This article discusses the pioneering work on personal microcomputers conducted at MCM in the early 1970s and, in particular, the making of the MCM/70 microcomputer.

Others picked up the story ( see the guide to further reading ) , but it was not until 1978 that the silicon chip became big news . Less than thirty years ago , electrical engineer J . Presper Eckert Jr . and physicist John W . Mauchly , at times assisted by as many as fifty helpers , laboriously built the world ' s first electronic digital computer . Their ENIAC ( Electronic Numerical Integrator and Computer ) was a fickle monster that weighed thirty tons and ran on 18 , 000 vacuum tubes - when it ran . But it started the computer revolution . Now under way is a new expansion of electronics into our lives , a second computer revolution that will transform ordinary products and create many new ones . The instrument of change is an electronic data - processing machine so tiny that it could easily have been lost in the pocket of one of those ENIAC tubes . This remarkable device is the microcomputer , also known as the computer - on - a - chip .
