TS2068 BASIC program that generates five TV test patterns for adjusting color TV sets and monitors: color bars (with color names labeled on bars), horizontal lines, vertical lines, crosshatch, and gray scale. Saved as SAVE “Patterns” LINE 1 for auto-run on reload; pressing any key returns to the menu. Notes that the TS2068 does not produce a standard NTSC signal, so patterns are useful for general adjustment but not for critical chroma alignment.
