Charles Babbage Unveils Difference Engine
June 14, 1822
In a paper to the Royal Astronomical Society, Charles Babbage unveils his design for a machine he called the Difference Engine, the first example of a mechanical computing machine. The British government funded the building of a Difference Engine, which Babbage never actually completed. However, Babbage’s design for the Difference Engine and his later Analytical Engine spurred future designs of working mechanical computers. In 1991 a working Difference Engine was constructed using Babbage’s plans, proving that his designs would have worked.
One Processor to Rule Them All
June 8, 1978
Intel introduces the 16-bit 8086 processor with clock speeds of 10, 8, and 5 MHz. The 8086 would become the basis for the series of processors used in “IBM Compatible” PCs and the x86 family (later marketed under the name “Pentium”) that would dominate the market in the PC era. Ironically, however, it was the modified 8-bit 8088 processor that was used in the original IBM PC, primarily due to factors that would reduce overall cost. The current line of Intel “Core” processors are still based on the same architecture that was introduced with the 8086.
Really Geeky Modem Technology Patented
June 7, 1983
Michael Eaton is granted a patent for the AT Command Set for Modems, which had created a standard language for interacting with modems. Two years earlier, the rights for this command set were purchased by the Hayes Corporation and incorporated into the Hayes Smartmodem 300 as the “Hayes Command Set.” The protocol will become an industry standard used for years to come.
In the early 90’s, needing to use modems so that I could connect to pre-Internet bulletin board systems, I learned the AT command set. I then used and supported modems extensively for about 15 years, and occasionally still do. Because I worked with modems so much, I used to be able to speak the AT command set in my sleep. I know, it impresses the ladies.
The Mac Gets Intel Inside
June 6, 2005
In a keynote address at Apple’s Worldwide Developers Conference, Steve Jobs announces that Macintosh computers will transition from PowerPC to Intel processors and demonstrates Mac OS X running on a computer with an Intel Pentium 4 processor. Jobs revealed at the time that Apple had been secretly preparing for a possible transition to Intel for many years. Unbeknownst to the public, for every version of Mac OS X released, Apple actually had prepared a version running on an Intel processor. By making the transition to Intel, Apple paved the way for the resurgence of the Macintosh computer by making it more compatible with software for Microsoft Windows.
