TIFRAC, India’s first computer — A retrospective

  • P. V. S. Rao
General / Article


To be associated with an important and challenging activity that is being carried out for the first time in the country is a truly memorable and satisfying, even if somewhat disquieting experience. I was privileged enough to have this opportunity when I was involved in the design and implementation of India’s first computer. TIFRAC (Tata Institute of Fundamental Research Automatic Calculator) — so was it named by Jawaharlal Nehru when it was formally commissioned in 1960 — was a truly a unique computer. Some of the features of this machine are described later in this article. It is also my intention in this article to convey some of the excitement, adventure and sense of accomplishment that the successful completion of this exercise brought to the design team.
