So, the channel has apparently launched early (at least in Michigan). First show I've caught was a 1984 (first season) Super Password with Bert Convy.
To answer the burning question: yes, the shows are totally unedited, all promotional plugs are intact, as are the credits. Currently up is the 1970s version of Card Sharks with Jim Perry. This must be some kind of demo version because the shows that are airing don't match up with the schedule Jamal had posted for Saturday.
There doesn't seem to be any paid advertisment yet as the commercial breaks have been showing little My Dinner With Andre style segments with Monty Hall and Wayne Brady, discussing Let's Make a Deal. They're also airing promos for their programming blocks, which I've seen footage of Dawson's Family Feud, Tattletales, Hall's Let's Make a Deal, the 1970s Match Game and black and white I've Got a Secret.
