Swordswoman Riding West On White Horse

can anyone give me informtion on a Jin Yong novel that was turned into 2 separate TV series? "SWORDSWOMAN RIDING WEST ON WHITE HORSE" the first was produced in the 1970's it was a hong kong production starring Yeung Pan Pan; the other series was a taiwan production from 1987 starring David Chaing Da Wei and Kelvin Kwan Chung. I'm interested in either or VCD/DVD (it doesn't matter if there are no english subtitles) I am very eager to purchase either one or both of them.;)
