Any info would be >appreciated. An article in the July 1992 issue of Cryptologia describes how some people cracked the codes that are 1 though 6 digits. The authors are Ken Shirriff (shirriff@sprite.berkeley.edu), Curt Welch (curt@kcwc.com), and Andrew Kinsman (kinsman@ssd.kodak.com). The VCR+ system is described in some detail in patent applications that were filed for patent protection outside of the US. For example, see PCT patent application PCT/US89/05806, published in publication WO 90/07844. It was published July 12, 1990. I hope this is helpful.
