There were computers in most workplaces and personal computers too but the world wide web wasn't developed yet until 1989. I believe the computer language was BASIC and Fortran.
Actually the crude version of the internet was invented way back in the early 1960s by the US military.
Emails did exist in the 1970s with colleges and universities where students could send messages to their lecturers.
My first full-time job in 1980 was in a small architectural firm and in the office upstairs used computers because I recall seeing a staff member using one. My knowledge of real computers was limited and all I knew about them was watching computers on sci-fi movies and the Star Trek series.
Those were the days where people would go to the local library for research and read many books about any topic. The rest was done manually with typewriters, pens, pencils, handwritten notepads, books, and heaps of paperwork.
I studied drafting and also had worked in an office where everything was drawn on tracing paper using ink pens and copied by a large printing machine. A coworker had told me about all plans, working drawings ( blueprints) in the future would be done by computers which in fact became Autocad in architectural offices in western countries.
Those were the good old days when people worked hard to earn a decent age and I recall being paid on Thursdays with an accountant coming around handing payslips ( an envelope with cash) to employees. I was never paid by a cheque.
