I'm quite sure it was wider than the screen (the game would have been really silly otherwise). The CGA let you set the virtual text screen width to practically any number. I think small values messed up the horizontal retrace, but large values were fine. I'll go find the code if you'd like. (What, don't you have a Technical Reference from DOS 1.00? Ya know, back in the days when the manual had a full BIOS listing? [grin]) ---Dan
