I am currently working on a book about the Danish Comet computer. I am neither a historian nor do I have any kind of formal training or experience that qualifies me to do this kind of work, so I have had to learn a lot during this process. This talk is all about sharing these experiences and telling the story about some of the weird places in which I uncovered information and sources for my book. The book is not yet finished, but you can read more about it online or get a general feeling of what I do by checking out my YouTube channel.
