NTSC carries a nominal visible picture area of 480 scan lines (240 per interlaced field), but 1970s-80s computers targeting it for display tended to use a smaller area for text/gfx because old TVs extended the picture *outside* the physically visible area to avoid borders, so things would get cropped.

The IBM PC's CGA used 200 scan lines; the Atari defaulted to 192 (but was capable of displaying the full 240 lines per field if you set up a display list with smaller borders!)
