Not in the UK. I was in small-town USA. I remember it being green, and the closest thing googling finds is VT100 by Louis Leff, which was, interestingly, written with Blazing Forth (I just learned this just now; I had no idea about Forth back then). I can't tell if VT100 actually had an 80 column mode, though...so it may have been another green-screened terminal program. I do remember it having an obscure (to me), technical-sounding name. It seemed like something out of Wargames.
