Oh god... I seriously don't remember whether Karate Fighter on C64 even had a jump move, but I certainly didn't use it.
Other than that, the first VG jump I really know of was in the old NES Castlevania (don't ask me which one), about '88/'89-ish, me being seven or eight. Some kind of family party at a friend's, and she (yay girl gamers) had Mario Golf, Castlevania and frickin' Ice Climbers! I was soooooooo close to peeing in my pants, rather than leave that marvellous toy alone...
