ICT 1301 computer

This computer was made in 1962, not of integrated circuits but individual transistors etc. I bought it in 1978. I and another member of the Computer Conservation Society are restoring it.

We are all very familiar with modern computers, but this shows how large (700 square feet), heavy (five tons), noisy, hot and hungry for electrical power (13kVA) the early computers were, their huge cost (about 250,000 pounds) and how much work it took to make them, program them, operate them and feed them with data. In the flesh, it also reminds those who worked on them of the unique smell of mainframe computers. It reminds us how cheap labour of the time was replaced by automation, on one hand freeing up clerks, managers, typists etc to do less boring work, though of course for many, redundancy seemed the end of their careers at the time.

    I thought there was a 1501 as well as I thought it was one that college got time on for me at Putney as the 1301 bought by the college was late on delivery.
