Those were the glory days of word processors, I used to have something similar on the Amiga. I'd still rather write on something like this than Word, Pages or Google Docs.
Word used to be a great product. Today it's a shambolic testament to incompetent design and dereliction.
Same, don't remember the name though. But it was WYSIWIG and I'd use it to create character sheets for our D&D games. And then I'd print them on a dot-matrix printer on continuous paper. Oh the memories!
