(Cupertino, CA) – During an unexpected joint press conference earlier today, Steve Wozniak and Apple Inc. (NASDAQ:AAPL) CEO Tim Cook announced that Apple will be releasing the long awaited Apple DOS 4.0 when the new iPad and iPhone lines are unveiled later this year. 

Dos 4.0 will wholly replace the iOS series of operating systems. It is reported that iPads runnning DOS 4.0 will stay powered for over 30 hours on a single charge, compared to around 10 hours for those running iOS. Other major features will be revealed over the coming weeks.  

The last major release of Apple DOS was version 3.3 in 1980. The original version of Apple DOS was written by Paul Laughton of Shepardson Microsystems in an outsourcing agreement with Apple. At the time, Steve Wozniak believed that he could write a better version; but Steve Jobs, Wozniak’s business partner, decided otherwise. “I really didn’t understand why Steve didn’t want me to write that code,” Wozniak remarked. “The other Steve, I mean. Its all about making great products and doing really cool engineering. I was never in this for the money, I just really love programming.”

Jobs was later ousted from Apple and then led the failed NeXT Inc. computer company before falling out of the industry altogether. Nolan Busnell, co-founder of Atari Inc, and long-time supporter of Steve Jobs said recently that “the best thing Steve Jobs ever did was to become friends with Wozniak. Wozniak is a brilliant engineer, a savant. I once tried to get Jobs to write a simple breakout-style game for me, and he would have failed if Wozniak hadn’t come in after hours and wrote it for him.”

Apple DOS was basically abandoned in 1983 when the focus turned to SOS for the beloved Apple III (an omen of sorts…?), and ProDOS for the Apple ][ line. Neither of these disk operating systems were considered innovative, or feats of engineering prowess. Wozniak lamented that he would not be able to show the world what a DOS could really be if it was designed by someone who truly loved the craft.

Now, with Apple Inc. (originally Apple Computer, Inc.) having celebrated the 40th anniversary of its incorporation in January of 1977, Tim Cook is betting that the time is right for Wozniak’s DOS 4.0. 

“We plan to have DOS 4.0 on all of our new devices this year, and to include DOS 4.0 in updates for all of our existing supported products by the end of the year. This will be a great year for Apple, and a redemption for our co-founder, ‘The Wiz,’ Stephen Wozniak.”

“It’s ‘Steve’, and ‘Woz’,” Wozniak replied with a smile. “But you can call me whatever you like. Wanna see my new Android app? Check it out in the Google Play store. I love Google’s open software concept. I posted the Apple DOS 4.0 code on github, and I welcome the community to provide comments and improvements so that we can make it the best DOS ever!”

According to Tim Cook, Wozniak will not be present at the unveiling of DOS 4.0 later this year, as he has a prior engagement.
