That same year in Germany, engineer Konrad Zuse built his Z2 computer, also using telephone company relays.]]> 2021-09-29 12:49:35 UTC https://padlet.com/27barkerc3/9xr3qrjr59nrk320/wish/1777875771 27barkerc3 https://padlet.com/27barkerc3/9xr3qrjr59nrk320/wish/1777888034 IBM´s 7000 series of mainframe computers are the company´s first to use transistors. At the top of the line was the Model 7030, also known as "Stretch." Nine of the computers, which featured dozens of advanced design innovations, were sold, mainly to national laboratories and major scientific users. A special version, known as HARVEST, was developed for the US National Security Agency (NSA). The knowledge and technologies developed for the Stretch project played a major role in the design, management, and manufacture of the later IBM System/360--the most successful computer family in IBM history.]]> 2021-09-29 12:53:33 UTC https://padlet.com/27barkerc3/9xr3qrjr59nrk320/wish/1777888034 27barkerc3 https://padlet.com/27barkerc3/9xr3qrjr59nrk320/wish/1777909786 Commodore releases the VIC-20 home computer as the successor to the Commodore PET personal computer. Intended to be a less expensive alternative to the PET, the VIC-20 was highly successful, becoming the first computer to sell more than a million units. Commodore even used Star Trek television star William Shatner in advertisements.]]> 2021-09-29 12:58:33 UTC https://padlet.com/27barkerc3/9xr3qrjr59nrk320/wish/1777909786 27barkerc3 https://padlet.com/27barkerc3/9xr3qrjr59nrk320/wish/1777913380 Japan's SoftBank introduces the first camera phone, the J-Phone J-SH04; a Sharp-manufactured digital phone with integrated camera. The camera had a maximum resolution of 0.11 megapixels a 256-color display, and photos could be shared wirelessly. The J-Phone line would quickly expand, releasing a flip-phone version just a month later. Cameras would become a significant part of most phones within a year, and several countries have even passed laws regulating their use.]]> 2021-09-29 12:59:37 UTC https://padlet.com/27barkerc3/9xr3qrjr59nrk320/wish/1777913380 27barkerc3 https://padlet.com/27barkerc3/9xr3qrjr59nrk320/wish/1777917643 Building a computer into the watch form factor has been attempted many times but the release of the Apple Watch leads to a new level of excitement. Incorporating a version of Apple's iOS operating system, as well as sensors for environmental and health monitoring, the Apple Watch was designed to be incorporated into the Apple environment with compatibility with iPhones and Mac Books. Almost a million units were ordered on the day of release. The Watch was received with great enthusiasm, but critics took issue with the somewhat limited battery life and high price.]]> 2021-09-29 13:00:53 UTC https://padlet.com/27barkerc3/9xr3qrjr59nrk320/wish/1777917643
