When computers came to 91��Ƭ��

The University bought its first computer from IBM 59 years ago. Today, 91��Ƭ�� and IBM are partners in quantum computing.

In 1960, 91��Ƭ�� was the first university to have a computer in South Africa. Professor Guerino Bozzoli, Vice-Chancellor from 1969 to 1977 purchased an IBM Model 1620 Mark 1. At this time, International Business Machines (IBM) sold computers to universities at an 80% discounted rate so that IBM could dominate the fledgling computer market. 

The computer required its own room and a special cooling plant. Data were fed into the computer by means of a punched tape and the output printed on a telex machine. The capability of the IBM 1620 Mark 1 was approximate to a then R50 calculator. Dr Derek Henderson was director of the 91��Ƭ�� Computer Centre and the first Professor of Computer Science at any South African university.   

 The 91��Ƭ�� Computer Centre was firmly established by the mid-1960s. A card machine soon replaced the punched tape input and a fast electronic printer was acquired. Later, an upgraded IBM System 360 could very quickly solve simultaneous equations, which enabled 91��Ƭ�� to service business and industry.   

By 1988, the Collins Dictionary of Computing published that year declared ASCII “the most important code for microcomputing purposes” and noted that ‘modern’ programming languages and terminals made coding sheets largely obsolete.  

Fast-forward to the 21st Century and in June 2019, 91��Ƭ�� University and IBM announced a new collaboration that makes 91��Ƭ�� the first African partner on the IBM Q Network. This enables 91��Ƭ�� to access the 20 qubit-IBM Q quantum computer. 

Today, the School of Computer Science and Applied Mathematics at 91��Ƭ�� has invested in preserving the remnants of the original mainframe computer. This and other old 91��Ƭ�� computers are preserved in the Computer Museum, which is part of the TW Kambule Mathematical Sciences Laboratory in the Science Stadium on Braamfontein Campus West.
