My first computer was a low-end PC which came with a 3M “Happy” office suite (my term, I have no documentation of the thing). It consisted of two 5,14 inch diskettes, one with “3M Happy Text” and one with “3M Happy Fakt” (German version). I don’t remember anything about Happy Fakt, but I recall 3M Happy Text pretty well. It was a simple, yet feature-rich text-mode editor, extremely intuitive with an in-program pop-up command line for macros etc.
It fit on a single 360kb disk, leaving plenty of space for other things and started pretty quickly, a refreshing novelty for programs at that time.
