Key Takeaways
- Steve Wozniak prioritized engineering innovation over corporate management at Apple.
- His open architecture philosophy was critical for Apple's early success and survival.
- Wozniak's generosity extended to sharing Apple IPO shares with excluded colleagues.
- He valued intrinsic engineering satisfaction above external recognition and wealth.
Deep Dive
- In 1976, Steve Wozniak offered his computer design to Hewlett-Packard; after rejection, he co-founded Apple with Steve Jobs.
- By 1980, Wozniak was a millionaire but prioritized engineering over company leadership.
- Wozniak's philosophy of open architecture, initially opposed by Jobs, proved crucial for Apple's survival.
- In 1971, Wozniak and Jobs explored 'phone phreaking' after discovering an article on making free calls.
- They researched technical manuals at the Stanford Linear Accelerator Center, locating a complete frequency list.
- Wozniak designed a digital tone generator after months of work, creating 'blue boxes' they sold for $150 each.
- Wozniak's paper designs, including the 'cream soda computer' and Pong/Breakout games, converged into a single vision for a personal computer.
- His design for the Apple I integrated a microprocessor with a TV display, a significant improvement over existing models.
- He built the prototype using a $20 MOS Technology 6502 processor in his HP cubicle; HP rejected the design but later released all claims.
- A design debate arose over the Apple II's expansion slots: Steve Jobs favored two, while Wozniak insisted on eight for user customization.
- Wozniak's insistence led to a compromise of eight slots, a decision he saw as his victory.
- Mike Markula agreed to invest $250,000, persuading Wozniak to resign from HP to officially incorporate Apple Computer in early 1977.
- Steve Wozniak designed the revolutionary Disk II floppy drive in two weeks, using the Apple II's main processor and fewer chips.
- VisiCalc, the first electronic spreadsheet, unexpectedly ran exclusively on the Apple II due to its technical specifications.
- This 'killer app' transformed the Apple II into a business machine, leading to a dramatic sales increase and shifting Apple's market to 90% business users.
- Following Apple's IPO on December 12, 1980, Wozniak sold his shares at a discount to 40 colleagues excluded from the IPO, calling it the 'Woz plan'.
- The Apple III, launched before the IPO, suffered from overheating due to Steve Jobs' mandate against cooling fans and vents, leading to system failures.
- Wozniak attributed the Apple III's failure to its design by marketing rather than engineers, contrasting it with the Apple II's open architecture success.
- IBM entered the personal computer market in 1981 with an open-architecture PC, quickly dominating the business sector.
- Steve Wozniak left Apple in 1985, returning to his engineering roots by finishing his degree, teaching, and funding educational initiatives.
- Wozniak's open architecture philosophy for the Apple II, characterized by its expansion slots, ultimately saved and transformed Apple into a valuable company.
