I remember reading that the Apple 2e was the first device with a switching power supply and the power supply design revolutionized power supply design for years to come. Is that true?
- bregma 5y agoIt's not true. Woz's genius switching power supply was what made the Apple ][ special long before the 2e was even dreamed of.
- TedDoesntTalk 5y agoApparently not, see link provided in the other reply: http://www.righto.com/2012/02/apple-didnt-revolutionize-power.html http://www.righto.com/2012/02/apple-didnt-revolutionize-powe... Jobs lied and, additionally, Woz did not design that power supply as you suggest.
- ruslan 5y agoIn the book "I, Woz", Steve Wozniak explains that Jobs hired a random hacker Rod Holt to design switching mode power supply unit for their Apple II computer. Jobs paid him $200 a day which was a lot of money by that time. Rod did the best work he could. https://en.wikipedia.org/wiki/Rod_Holt https://en.wikipedia.org/wiki/Rod_Holt

- TedDoesntTalk 5y agoThis was amazing to read. Thanks for correcting me and string the record the straight for me. Jobs was not telling the truth.
