Computers

November 29, 1974

The January Issue of Popular Electronics is published, featuring the MITS Altair 8800 microcomputer kit on its cover. The magazine would begin arriving on newsstands and to subscribers in the first part of December. The Altair 8800 itself would begin shipping on December 19th. The visibility that the Altair received helped make it an extremely popular computer for its time, as MITS forecasted selling 800 computers over the course of one year and ended up selling 5,000 units by August. As the magazine started reaching readers, MITS was flooded with inquires and orders for the Altair to the point where they had to hire more people just to answer their phones. The success of the Altair helped popularize the concept of the microcomputer, which then inspired early technology innovators such as Steve Wozniak and Steve Jobs who created the Apple I personal computer, as well as Microsoft founders Bill Gates and Paul Allen who wrote software for the Altair and other early micro and personal computers.

The story behind the collaboration of MITS and Popular Electronics for this particular issue is interesting. The recently hired editor of the magazine wanted more computer projects to be featured yet knew that existing microcomputer projects of the time were somewhat daunting for hobbyists to complete. They were looking for something that was a complete kit in a professional-looking enclosure. Another editor knew that MITS was working on a project that could fit their need and collaborated with them to have the kit ready for the January issue publication. While the first prototype was ready in October and was shipped to Popular Electronics, it never reached them due to either a strike by the shipping company or simply being lost or stolen (the story varies depending on the source). The article was actually written using pictures of an empty mock-up of the Altair and a prototype circuit board layout that was different than the finished product. Additionally, MITS left the naming of the microcomputer kit to the magazine. One of the editors claims that the inspiration for the name came from this 12-year old daughter who suggested calling it Altair after the location where the Star Trek Enterprise would be traveling in that night’s episode. However, other sources claim it was a technical editor of the magazine who came up with Altair when it was suggested the computer be named after a star. Whatever the truth is, the Altair 8800 was one of the most important computers in technology history and we all owe a great deal to this particular magazine issue for publicizing it.

Douglas Engelbart receives US patent 3,541,541 for his “X-Y Position Indicator For A Display System”, more commonly known as the computer mouse. Engelbart called his device a “mouse” because the cord looked like a tail. The mouse was first prototyped in 1964, but wasn’t demoed until 1968, and was not included with a commercial computer until the Xerox 8010 Star Information System in 1981. Apple first brought the mouse to a personal computer with the Lisa in 1983. However the mouse did not become ubiquitous until after 1984, when Apple’s Macintosh popularized the device.

The prototype of the first mouse

An advertisement in the magazine Electronic News announces the Intel 4004, the first commercially available microprocessor. The 4004 was primarily used in calculators, the first being the Busicom 141-PF. In fact, it was Busicom that actually developed the design of what would become the Intel 4004. Busicom approached Intel to help them finalize the design and manufacture their “calculator engine”. Intel’s engineers reduced the 12 integrated circuit design Busicom had come up with to 4 ICs and delivered the finished product in January 1971. Busicom had exclusive rights to that design until later in that year, when Busicom and Intel renegotiated their contract with Intel lowering their prices to Busicom in exchange for rights to the design of the microprocessor.

By offering the first general-purpose programmable processor to the general market, Intel spurred the rapid development of electronic devices in the 1970s, culminating in the development of personal computers during that decade. However, Intel wasn’t the clear leader in the microprocessor market until the IBM PC and clones helped catapult Intel to that title in the 1980’s.

One week after reports surfaced identifying a flaw in certain Pentium processors, Intel releases a software workaround for operating systems to avoid the commonly named “F0 bug“. A very specific invalid operation passed to the affected processors would cause the processor to lock up, causing the computer and any software running on it to freeze. Identified by Intel as the “Invalid Operand with Locked Compare Exchange 8Byte (CMPXCHG8B) Instruction Erratum” (seriously?), the flaw, while potentially a serious problem, was practically little more than a PR headache as the invalid operation that triggered the processor to lock up was never encountered in real-world operations. Additionally, the F0 bug only affected the older Pentium processors, not the Pentium II and Pentium Pro processors Intel was currently shipping at the time. However, the workaround was necessary as malicious software could have exploited the flaw and caused serious problems for PCs and servers using the affected processors.

Robert Metcalfe’s Original Ethernet Concept

November 11, 1973

As invented by Robert Metcalfe and David Boggs, an Ethernet network functions for the first time. From it’s humble beginnings as a research project at Xerox PARC, Ethernet has developed into the de facto standard for business and home networking.

Compaq announces their Compaq Portable PC, one of the early portable computer designs and, more significantly, the first successful IBM-compatible PC clone. Compaq eventually succeeded where other similar companies failed because they took considerable care in creating their product on two fronts. First, they created the first 100% IBM-compatible BIOS, the only proprietary component of the IBM PC. Spending $1 million to reverse engineer the IBM BIOS using clean-room techniques, this also allowed them to avoid copyright infringement charges. Finally, they were legally and financially prepared for the inevitable lawsuit IBM would bring against then, which was dismissed as expected.

By proving that a clean room, reverse-engineered BIOS could create 100% IBM-compatible computers and withstand legal challenges from IBM, Compaq paved the way for the flood of IBM-compatible clones that would begin in the mid-1980’s. This was the opening of the Pandora’s Box that led to IBM losing control of the platform, and the emergence of Microsoft and Intel as the dominant technology companies of the PC era. Even though IBM lost control of the platform they created, the weight of the IBM name combined with the eventual low cost of the IBM-compatible platform crushed nearly all other competing personal computing platforms of the era.

As part of a publicity stunt to help boost sales, Remington Rand collaborates with CBS to have its UNIVAC computer predict the results of the 1952 US presidential election between Dwight Eisenhower and Adlai Stevenson live on air. Because the pre-election polls had the election very close, the publicity surrounding a computer predicting the winner generated a lot of popular interest.

UNIVAC correctly predicted a landslide victory by Eisenhower early in the evening after only 3 million votes had been returned and entered into the system. However, because it was so different than the expected result, the decision was made to hold back the computerized prediction. It appears that both Remington Rand and CBS feared the computer was incorrect so they didn’t want to take the risk. It was only late in the broadcast when continuing returns seemed to indicate that UNIVAC was in fact correct, did CBS announce the landslide prediction from the computer and the fact it had done so hours earlier. In the end, UNIVAC had come within 3.5% of the popular vote, within 4 electoral votes, and predicted 100-1 odds of the Eisenhower victory.

The publicity stunt worked as UNIVAC became relatively famous. For a time people started calling all computers “UNIVACs”, it was featured on the cover of a Superman comic book, and in a Looney Toons cartoon. By the next presidential election 4 years later, all 3 major networks were using computers to predict the results.

According to Dan Bricklin, the first “real” release of VisiCalc was completed and packaged for shipment. VisiCalc was the first commercially available spreadsheet software and quickly became the first “killer app” of the personal computer market.
