I’ve been working in ICT since 1974, so I have seen a lot of changes. I started out by learning Cobol programming for ICL 1900 Series mainframes, then taught programming for several years. In 1975, I had my own personal mainframe computer, because the college I worked for had acquired one, but didn’t even know how to turn it on. They asked me to figure it out, so I worked through the library of manuals, and got it working.
