SuperWriter!
I started off in the good days of 1986 at the local ITeC too, we were taught how to use SuperWriter as well as WordStar. The fun came when we all got called in to see who was going to own up to hex editing the SuperWriter disk to SuperW**nker. It only came to light when they ran an evening class!
Fond memories of the BBC though, we spent a lot of time back then ripping off eproms for our BBC's at home ;-)
