I don't really remember much about the contents, it was too advanced and foreign for me back then. It was hard cover, pages of about A4 size, the cover was gray with thin white horizontal lines. One of the pages contained the famous photo of "first actual case of a bug". The illustrations were in the 80s corporate style with subtle gradients.
