Only remember seeing this show in the summer of 1979 on Camp TV Ontario (Camp TVO, Camp TVOntario). I seem to recall this being a ten-part series. A group of kids - maybe 4 or 5 of them, maybe around 12 -14 years old had this place they hung out at - looked like it was a clubhouse of some type. Inside the clubhouse was some computer/transporter that took them to different situations. In each episode, two or three of the kids were transported somewhere different and the people left at the clubhouse had to figure out how to get them back. One place some of the characters were sent to - was a country where people were doing things backwards. They torn down new buildings and put up old ones. There was always someone messing around with them trying to sabotage their efforts in coming back - in this case it was the Mysyery Man - who was the Mystery Man? It was Billy Van dressed up in a red outfit, with a big letter M on his chest! You just don't get programs like this anymore!
