Stock OS-9 Level I did not. O-Pack from Frank Hogg Labs, and some other third parties, were sold as add ons for such things.

Bill (the one asking the question) - if you are running Level II, you change the term screen from 80 column to 40 column with:
display 1b 24 1b 20 1 0 0 28 18 0 2 2 to get a 40x24, white on black screen, if that helps (pretty sure I have that right. If you change the 18 to a 19, you can get 25 rows instead. The last 3 digits are your foreground, background, and border colors respectively (0-F), based on your current palette settings in NitrOS9.
