Improve a 1993 Brother-brand Word Processor?

I'd like to make my 1993 Brother word processor useful. It looks like a laptop with a small black-text-only screen and handles a few basic programs (Tetris, word processor, spreadsheets). I've seen great Instructables for later laptops, but nothing that would work for mine, since it doesn't have a color screen and probably has a pretty small memory bank. Ideas?
