Jim Clark — the Netscape Communications co-founder dubbed “the comeback billionaire” for betting on Apple — is in contract to buy the famed forty foot wide Mellon mansion on the Upper East Side.

Ironically, Clark — a former Stanford University prof — got rich coming up with his 1994 Netscape concept to be the first to capitalize on the World Wide Web with slogans like, “the web is for everyone.”

The stately mansion, at 125 E. 70th St. was created by Paul and Bunny Mellon in 1965. It is in need of extensive multimillion dollar renovations, sources say.

The mansion was originally asking $46 million and was recently reduced to $41 million. It is currently in contract for around $39 million, several sources told The Post.

The eight bedroom, eight bathroom residence comes with five half baths, five fireplaces, a library, wine cellar, grotto, and gardens “with a reflective pool and gazebo,” according to the listing.

Bunny loved to garden in her Manhattan backyard. She was pals with Jacqueline Kennedy Onassis, and even designed the White House Rose Garden.

Featured in The World of Interiors magazine, the townhouse was designed in a neo French classic style, according to the listing.

The mansion boasts high ceilings, a drawing room and dining room that leads to a terrace, along with a chef’s kitchen and an elevator.

It was designed specifically for the Mellons and their “distinct needs,” a source said. That means lots of space for servants and “tiny bedrooms” for children.

The block also holds 115 E. 70th St., the renovated mansion that fashion designer Reed Krakoff sold earlier this year for a whopping $51 million.

That 7-story mansion was built in 1910 and is 18,000 square feet.

Clark lost some of his wealth following the 2008-2009 economic crisis.

However, he gained it back by buying Apple stock in 2009 and on. He was also a big investor in Facebook — $40 million — and Twitter — $30 million, according to Forbes.
