Back in the early-80s, on Saturday mornings, if my dad didn't drag me off to work with him (he was a plumber and electrician) -- I would stay home and watch the Weekend Specials on ABC. I had many favorites: "Land of Og" (about those little green guys who lived under ground); "Zack and the Magic Factory (the beginning was so intriguing -- the boy arriving by taxi at night at the front of this ominous-looking building, and the creepy monster and gadgetry guarding the inside of entranceway -- scared the be-Jesus out of the boy, riveted me to the sofa); and "The Haunted Mansion Mystery" (where the boy and girl are trapped under an old mansion in a secret room, which they think is haunted by the spirit of a rich old man -- who one day, miserly, hauled his money home from the bank in a wheelbarrow and died there, leaving his skeleton to entertain the boy and girl in the secret room). They just don't make programs for children of that quality anymore. I could mention many other shows, but I don't think there is space enough here.
