Please ID this 70's kid's show!

I have vague memories of a 70’s live-action kid’s show starring a Doug Henning lookalike and some sort of computer vith a video screen. For no particular reason I have been driving myself nuts the past few days trying to remember the title.

It may have involved three "M"s (ie Marvin and the Magic Machine or something similar).

The only other detail I can add is that I think one of the episodes involved a flight on Concorde.

Googling has proved fruitless, as you may imagine with so little to go on.

Help please…

That would be Marlo and the Magic Movie Machine, starring versatile voice actor Laurie Faso.

Thanks JThunder, that’s the one.

Google has failed to find me a photo but I have learned that Mr Faso has also been a Transformer, GI Joe, and a number of Monchichis. Versatile indeed!

And another lurker breaks cover!

Okay, here’s another: weekday afternoon show, set at a haunted castle. It featured a host/narrator that in my adult mind reminds me of the Crypt Keeper. It mixed live action, cartoon and puppets/marionettes, as near as I can remember. It was sort of like a Goth Banana Splits, I think. Aired in the early-to-mid-70’s.

Could it have been the *Groovy Ghoulies*? I remember this show but don’t recall any live action or puppets.

By the way, thanks for noticing, Baker. I had held out for a momentous first post but eventually gave up.

No, it wasn’t the Ghoulies. I do remember that show, though. It might have been a regional thing (Virginia).
