At my age, people gladly remember all sorts of their beginnings. So do I gladly remember my beginner's work in the area of informatics. I hope that these memories will not be damaged by my number of neurons. In these memories I will talk about my first employment, analogue computer, designing digital computers, software development and teaching computer science. The memories encompass the period from 1950 to 1980. Of course, many things happened after this period, and especially important is invention of personal computers. But it might be another story.
