Webnode (1999)

Although Webnode was not yet a publicly trade company, the press release declared that shares in the company could be reserved for later purchase, although no payment would currently be accepted. Because the Next Generation Internet was a real government project, many were led to believe that Webnode was also real (which, of course, it wasn't). Business Wire, however, didn't find the prank amusing. It sued the creators of the press release.

Left-Handed Toshiba (1997)
Declaring that "there's nothing looney about the lefties," Toshiba announced the new "Toshiba Tecra F00-LDU" — a portable computer designed for left-handed users:The F00-LDU is a fully functional notebook packed with all the features you'd expect from the world leader in portable computing — only it fits left handed people like a glove. The major bays and keys are reversed for clarity and there's a stunning left handed screen."

Internet Spring Cleaning (1997)

The joke was an updated version of an old one that used to be told about the phone system. For many years, gullible phone customers had been warned that the phone systems would be cleaned on April Fool's Day. They were cautioned to place plastic bags over the ends of the phone to catch the dust that might be blown out of the phone lines during this period.

Blue Can Warning (1996)

Virgin Cola announced that in the interest of consumer safety it had integrated a new technology into its cans. When the cola passed its sell-by date, the liquid would react with the metal in the can, turning the can bright blue. Virgin warned that consumers should therefore avoid purchasing all blue cans. Coincidentally, Pepsi had recently unveiled its newly designed cans which were bright blue.

Moore’s Law Rewritten (1990)
Intel employees circulated a spoof newsletter revealing historical discoveries related to chip-making, such as the fact that archaeologists had uncovered evidence of the existence of chip-making factories in Ancient Egypt. The newsletter quoted eminent archaeologist Lord Dhrystone as saying, "We never imagined we'd find an active semiconductor industry in a major goat-herding area. Too much dust." The newsletter also revealed the unknown origins of the famous "Moore's law." Apparently Gordon Moore, Intel Chairman, had once scribbled on the back of a phone bill the phrase 'Buy Intel chips. They'll get twice as big every year or so,' as he brainstormed about ways to get people to buy more Intel chips. It was his secretary, Jean Jones, who rewrote the phrase to the more famous, "The number of transistors on a chip will double every 18 months."

Driver’s Weight Sensors (1989)
BMW unveiled a "significant advance in anti-theft technology" — Driver's Weight Sensors:"DWS stands for Driver's Weight Sensor. A unique system that compares the driver's weight with a pre-programmed value stored in the sensor's computer memory...
The sensor weight reading is then compared to the programmed weight in the memory, and provided this falls to within ±5%, the car will start normally.
If, however, the figure exceeds these tolerances, then a discreet gong sounds, and the entire ignition system is shut down."<
Interested readers were urged to contact Hugh Phelfrett at BMW.

First Photograph Discovered (1987)
The camera manufacturer Olympus announced that it had discovered "the first picture ever taken." The picture was supposedly discovered in the Japanese "Outer Fokus mountains." The Guardian, collaborating in the joke, ran an article about the discovery on its front page.

Soybean Computer Disks (1985)
Byte Magazine featured a section called "What's Not," instead of its usual "What's Hot" section. Included were technological gadgets such as computer disks made of soybeans:If merely erasing sensitive data is not enough for you, Soycure Systems of Tokyo has developed the ultimate in disk security. Made entirely of processed soybeans, Parasoya Disks are writable, readable, and edible. Parasoya disks contain 84 percent more protein than average floppy disks and are available in 5¼-inch (regular) and 3½-inch (crunchy) formats.

The MacKnifer (1985)
Byte magazine also described a new product called the MacKnifer: A hardware attachment that mounts on the side of your Macintosh and sharpens knives, scissors, lawn-mower bladesanything in your home that needs sharpening... Turn your spare computing time into extra cash with a knife-sharpening business on the side... of your Macintosh.

Finally, Byte magazine featured a new portable computer, available from the Honda Corporation, called the "Transporter":
Byte later received a call from a USA Today reporter inquiring about the Transporter.
The first truly transportable computer. With a few simple twists, you can transform the Transporter from a portable computer (with full keyboard, 24-line by 80-column display, and two microfloppy-disk drives) into a single-passenger automobile... The Transporter is 100 percent compatible with the popular Toyota Corolla and runs on most operating roads.
Byte later received a call from a USA Today reporter inquiring about the Transporter.

The 5-megabyte Hard Drive (1982)
In its "What's New" section Byte Magazine announced the introduction of a 5-megabyte hard disk for the Sinclair ZX81:Responding to an obvious need of ZX81 owners for more data storage space, Hindsight Engineering has developed a 5-megabyte hard-disk system for the Sinclair ZX81. The system is available in either assembled or kit forms. The kit includes instructions for building your own clean room for kit assembly. A DOS will soon be available.
At the time, 5 megabytes seemed like an impossibly large size. Nevertheless, hundreds of readers wrote to the magazine requesting more information.

Erase-Only Memory (1982)
Byte Magazine also described an "erase-only memory" circuit in it's "What's New" section:The Stanislowski Electronics 3131.3 is a 4 Kbyte, vigorous, random-access erase-only memory (RAEOM) Imaginary Metal Oxide Semiconductor (IMOS) integrated circuit (IC)... Possible applications include disposing of obsolete data and programs, destroying incriminating evidence, and amusing computer hobbyists. Due to the patented IMOS process, the 3131.3 remains fully functional even when power is removed, making it ideal for use during power blackouts.

Debugging Tool (1982)
A third April Fool's day product featured by Byte magazine was a Debugging Tool that "Irons Out Circuit Problems":The General Electric Model F340 Electric Iron serves as a handy debugging tool for crucial logic circuits that must exhibit planar topology or use especially thin-film substrates. Using the latest deionized-vapor-injection technology, the Model F340 can be used with circuits arrayed on fiber substrates up to 0.1 cm (approximately 1/8 inch) thick, assuming proper adjustments for duration of treatment.

The Black-Hole Diode (1981)

Another new addition in the small-components market is the 7N-∞ BHD (black-hole diode). This device has two inputs and no output. Care must be taken to shield this component appropriately or it may absorb the unit it is placed in. The 7N-∞ will accept any voltage or current value. It is useful for GI (garbage-in) applications. Due to the light-absorption qualities of the device, we could not provide a photograph. Contact Spatial Regression Ltd, POB 463, Paulborough NH 03458.

Byte Magazine published a technology update describing, in highly technical language, an invention that it called the “first practical Touring Machine” (which bore a strong resemblance to a bicycle):This month in the hills of New Hampshire, we discovered an example of computer technology in the form of the first practical Touring Machine, shown here complete with a unary relocatable based operator (in IBM OS PL/1 parlance). For those individuals having less than a passing acquaintance with computer science, the Turing machine is a famous mathematical construction first formulated some decades ago by Alan Mathison Turing, and which can be shown to be logically equivalent to any digital computer implementation. A Turing Machine is to computing what a Carnot cycle is to thermodynamics. (The fact that this particular Touring Machine implementation looks like a CarNot Cycle is purely incidental.) But Turing machines have been notoriously impractical in terms of everyday computer usage until this new product rolled into town. This newly released virtual Touring Machine, version 27 chain level 1, incorporates numerous state of the art features which make it one of the better examples of the form.
