Need some help figuring out a series (possibly television) that was about a couple of kids who's dad gets sucked into another dimension through a pinball machine. The series is probably from the late 70's/early 80's and was shown in some school classrooms. I believe the PBS show from a few years ago 'Mythquest' was based on the show I am trying to find out about. It has the same plot - kids dad gets sucked into computer and they go on adventures through time trying to rescue him. If anyone has a clue as to what the name of this show is, I would appreciate it. It was probably a PBS show back in the 70's or 80's. Thanks!

Mythquest is the only show that rings a bell with me. If you think it might be a PBS show, take a look at this link. It lists all the programs shown on PBS, past & present. Maybe the name will jump out at you.
