Informative 1960 video (enhanced) about IBM 1401 which I think I had heard/read about in early 1980s in my student days in Bombay/Mumbai, even before I got into software field: Computer History: IBM 1401 Mainframe Data Processing System 1960 ENGLISH version (HD), https://www.youtube.com/watch?v=UZIIMElB2Wo , 8 min. 17 secs. 

[I did B.Sc. Physics followed by half a year or so of M.Sc. Physics (in 1983-84) before I dropped out of M.Sc. Physics and started looking out for a job in software field.] I think IBM 1401 was the first computer model name that registered in my mind. But I have never physically seen an IBM 1401.

https://en.wikipedia.org/wiki/IBM_1401 tells us, "During the 1970s, IBM installed many 1401s in India and Pakistan where they were in use well into the 1980s." I think that explains why I had heard/read about IBM 1401 in the early 1980s in my student days. I think the electric (& transport) company in Bombay then - BEST, https://en.wikipedia.org/wiki/Brihanmumbai_Electric_Supply_and_Transport - used an IBM 1401.
