The premise of this proposed 1978 TV series doesn't sound that bad, but only one pilot episode was ever made. NBC decided not to pick up the full show. Description from ioffer.com:
Scientist Simon Shane (Hindle) is working on a project which will create human clones of himself. Years of failed experiments with his mentor (Bellamy) at his side have yielded breakthroughs but not a successful final product though one is set to be unleashed within days. With his mentor kidnapped and a mysterious new party having presented itself with designs on the project which are suspicious at best, Simon accelerates the project and clones himself a dozen times maintaining a telepathic link with each of his fully grown "children" each of whom is an exact replica of him with all of his memories and capabilities.
Unfortunately, the full pilot episode isn't available anywhere online. A clip is all that YouTube has.
The show was written by Frederik Pohl, who had this to say about it in a 1977 interview with Tangent magazine
TANGENT: What do you think of science fiction expanding into all of the different media? We have the records, tapes, comic books, television, etc. plus the books.
POHL: I think that the other media are peripheral. I get involved in them from time to time. I’m making a record and I have a contract to do the pilot script – and the treatment – for a new television series. It’s called “The Clone Master” at the moment. It’s not an anthology series, it’s a series series. They trapped me into it by promising me that it would be an anthology series. Now, this is one that I generated. The producer asked me for some suggestions and I told him that it should be an anthology series and ultimately badgered me down to where I am now. The process is one of badgering down. You get into television and you find there are twenty-five people who are being paid to criticize what you do and they all have to justify their salaries. It’s no fun, I don’t like doing it. I do like it in the sense that I like experimenting on my own in areas that I haven’t done before.
