How to Tell

 * Several Columbia Pictures Videocassete Services-duplicated tapes from 1979 to 1981 have the color bars test pattern with the normal-pitched looping beep-tone at the end of the tape. On some tapes printed very early during 1979, there is a black screen with the text, "This is a TEST!" and a similar looping beep-tone in a slightly low or normal pitch.
 * On some early tapes, "910" is etched somewhere on the tape. It could also be a year-month code, in this case, October 1979.
