The Canon Cat After of Release Before Macintosh
LORI EMERSON & FINN BRUNTON THE CANON CAT PROCESSING ADVANCED WORK In the fall of 2014, Finn Brunton, an assistant professor at NYU, contacted Lori Emerson, Director of the Media Archaeology Lab (MAL) at the University of Colorado, Boulder, about a rare fi nd he came across on ebay: a Canon Cat, which billed itself in 1986 as an “advanced work processor.” The MAL wasn’t immediately able to purchase the machine; however, Brunton purchased the Canon Cat with the agreement that he’d experiment with the Canon Cat for six months or so, sell it to the MAL, and then he and Emerson would co-write a piece – now, this piece – on the obscure machine from an ever-more distant past. Here, we hope to give you a glimpse into what computing could have been and still could be. 353 [SHIFT]+[DOCUMENT] [SHIFT]+[DOCUMENT] Who will the user be?

Atari’s Pong, a simple Mall in San Jose, California, dressing up electronic version of ping-pong, had caught on like wildfire in arcades as Alice In Wonderland characters. Jobs and homes across the country, and Bushnell was anxious to come up and Woz alternated as the White Rabbit with a successor. He envisioned a variation on Pong called Breakout, and the Mad Hatter. in which the player bounced a ball off a paddle at the bottom of the screen in an attempt to smash the bricks in a wall at the top. Bushnell turned to Jobs, a technician, to design the circuitry. Initially Jobs tried to do the work himself, but soon realized he was in way over his head and asked his friend Steve Wozniak to bail him out. “Steve wasn’t capable of designing anything that complex. He came .atarihq.com) “He was the only person I met who knew more about electronics than me.” Courtesy of Atari Gaming Headquarters (www Courtesy of Steve Jobs, explaining his initial fascination with Woz “Steve didn’t know very much about electronics.” Conceived by Bushnell, Breakout was originally designed by Wozniak and Jobs.

Retrocomputing As Preservation and Remix
Retrocomputing as Preservation and Remix Yuri Takhteyev Quinn DuPont University of Toronto University of Toronto [email protected] [email protected] Abstract This paper looks at the world of retrocomputing, a constellation of largely non-professional practices involving old computing technology. Retrocomputing includes many activities that can be seen as constituting “preservation.” At the same time, it is often transformative, producing assemblages that “remix” fragments from the past with newer elements or joining together historic components that were never combined before. While such “remix” may seem to undermine preservation, it allows for fragments of computing history to be reintegrated into a living, ongoing practice, contributing to preservation in a broader sense. The seemingly unorganized nature of retrocomputing assemblages also provides space for alternative “situated knowledges” and histories of computing, which can sometimes be quite sophisticated. Recognizing such alternative epistemologies paves the way for alternative approaches to preservation. Keywords: retrocomputing, software preservation, remix Recovering #popsource In late March of 2012 Jordan Mechner received a shipment from his father, a box full of old floppies. Among them was a 3.5 inch disk labelled: “Prince of Persia / Source Code (Apple) / ©1989 Jordan Mechner (Original).” Mechner’s announcement of this find on his blog the next day took the world of nerds by storm.1 Prince of Persia, a game that Mechner single-handedly developed in the late 1980s, revolutionized computer games when it came out due to its surprisingly realistic representation of human movement. After being ported to DOS and Apple’s Mac OS in the early 1990s the game sold 2 million copies (Pham, 2001). -
IEEE Spectrum: 25 Microchip
IEEE Spectrum: 25 Microchips That Shook the World http://www.spectrum.ieee.org/print/8747 Sponsored By Select Font Size: A A A 25 Microchips That Shook the World By Brian R. Santo This is part of IEEE Spectrum 's Special Report: 25 Microchips That Shook the World . In microchip design, as in life, small things sometimes add up to big things. Dream up a clever microcircuit, get it sculpted in a sliver of silicon, and your little creation may unleash a technological revolution. It happened with the Intel 8088 microprocessor. And the Mostek MK4096 4-kilobit DRAM. And the Texas Instruments TMS32010 digital signal processor. Among the many great chips that have emerged from fabs during the half-century reign of the integrated circuit, a small group stands out. Their designs proved so cutting-edge, so out of the box, so ahead of their time, that we are left groping for more technology clichés to describe them. Suffice it to say that they gave us the technology that made our brief, otherwise tedious existence in this universe worth living. We’ve compiled here a list of 25 ICs that we think deserve the best spot on the mantelpiece of the house that Jack Kilby and Robert Noyce built. Some have become enduring objects of worship among the chiperati: the Signetics 555 timer, for example. Others, such as the Fairchild 741 operational amplifier, became textbook design examples. Some, like Microchip Technology’s PIC microcontrollers, have sold billions, and are still doing so. A precious few, like Toshiba’s flash memory, created whole new markets. -

Professor Won Woo Ro, School of Electrical and Electronic Engineering Yonsei University the Intel® 4004 Microprocessor, Introdu
Professor Won Woo Ro, School of Electrical and Electronic Engineering Yonsei University The 1st Microprocessor The Intel® 4004 microprocessor, introduced in November 1971 An electronics revolution that changed our world. There were no customer‐ programmable microprocessors on the market before the 4004. It propelled software into the limelight as a key player in the world of digital electronics design. 4004 Microprocessor Display at New Intel Museum A Japanese calculator maker (Busicom) asked to design: A set of 12 custom logic chips for a line of programmable calculators. Marcian E. "Ted" Hoff Recognized the integrated circuit technology (of the day) had advanced enough to build a single chip, general purpose computer. Federico Faggin to turn Hoff's vision into a silicon reality. (In less than one year, Faggin and his team delivered the 4004, which was introduced in November, 1971.) The world's first microprocessor application was this Busicom calculator. (sold about 100,000 calculators.) Measuring 1/8 inch wide by 1/6 inch long, consisting of 2,300 transistors, Intel’s 4004 microprocessor had as much computing power as the first electronic computer, ENIAC. 2 inch 4004 and 12 inch Core™2 Duo wafer ENIAC, built in 1946, filled 3000‐cubic‐ feet of space and contained 18,000 vacuum tubes. The 4004 microprocessor could execute 60,000 operations per second Running frequency: 108 KHz Founders wanted to name their new company Moore Noyce. However the name sounds very much similar to “more noise”. "Only the paranoid survive". Moore received a B.S. degree in Chemistry from the University of California, Berkeley in 1950 and a Ph.D. -
