Things were more laid back in the 70s. I was sitting in an outside office waiting for my fiance who was interviewing for a post when the interviewer’s door opened and I was asked “Do you know what a computer is?”. Well, I did … I’d had a job a couple of years previously inputting bubble-chamber data into a big IBM mainframe in Birmingham University and had been shown the computer, and at college I had run one FORTRAN program from a deck of punch cards, so yes, I did know what a computer was! The next week I started my new post as Trainee Computer Programmer (COBOL). And I hadn’t even gone for a job. Then I started reading IBM training manuals, Computing, Computer Weekly and Datalink. Passing that test kept me busy for the next 45 years.
