December 12, 1980: Apple goes public, floating 4.6 million shares on the stock market at $22 per share.

In the biggest tech IPO of its day, more than 40 out of 1,000 Apple employees become instant millionaires. As Apple’s biggest shareholder, 25-year-old Steve Jobs ends the day with a net worth of $217 million. However, the big payday triggers internal tensions as it highlights Cupertino’s class divide.

A midrange model of Apple’s new iMac Pro comes with a massive 11 times as many bytes of electronic memory as the Apple II, the company’s first breakthrough computer.

Doesn’t sound all that impressive? We’re not just talking about a single Apple II unit. Instead, that figure refers to the sum total of all electronic memory ever installed on all 6 million Apple II computers ever built!
