One Processor to Rule Them All

Intel 8086June 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

Hayes Smartmodem 300June 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

Mac OS X PowerPC and IntelJune 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.

The Apple II Enters the Market

The Original Apple IIJune 5, 1977

The original Apple II computer goes on sale. The Apple II featured an a 1MHz MOS 6502 processor, an integrated keyboard, a built-in BASIC programming environment, expandable memory (4K expandable to 48K), a monitor capable of color graphics, a sound card, and eight expansion slots. To include all these features in one discrete unit was highly innovative and the reason it is considered the first practical personal computer. However, in the spirit of the original computer hacker, the Apple II was also available as a circuit-board only, without keyboard, power supply, or case. A couple of years later, the combination of the Apple II series and the first “killer app” of the business world, the VisiCalc spreadsheet program, popularizes personal computers among business users. This sudden success of the “home computer” in the business world surprises established technology companies and eventually leads IBM to scramble to develop their IBM PC.
