Lotus 1-2-3 dates back to the early 1980s and was early spreadsheet software which was important in the development of IBM computers. Anyway, that’s a story for elsewhere to be told by people who know much more about it than me. The only reason I’ve posted this is that I remember using this software at school, and remember the packaging of the box. I really do need to get out more. And, I’m realising that I’m definitely ageing slightly if I’m seeing software that I once used in a museum.
