The original Mac development and design team is under the picture of Steve Jobs, a picture from the famous 1984 Mac commercial is above the head of Steve Wozniak, at the golden mean there is the first full page ad for the Macintosh computer that was in the Wall Street Journal. The collage displays some of the historical symbols (microprocessors and pulldown menus) that were unique for the Mac back in the 1980s.

MacPaint By Ben Bonaccio
I’m going to date myself here: I wasn’t around for the release of MacPaint in 1984. While I didn’t get to use the revolutionary UI based drawing software until I arrived on the scene in ’88, it still had a profound impact on my interest in using the computer as a creative and artistic medium.
For those who were around for the 1984 release which coincided with that of the original Macintosh, MacPaint’s impression was likely even greater. As the precursor to almost all modern imaging software, MacPaint introduced tools such as the “lasso” and “the paint bucket” (which I called “the paint leaker” as a kid). The “marching ants” selection boxes commonly seen in Adobe software also got their start with MacPaint.
Though it may seem like second nature to us today, Apple’s drawing software was the first to let users generate images by interacting with a GUI as opposed to working with code behind the scenes.
Realizing MacPaint’s technical and historical significance, Apple donated the original source code to the Computer History Museum a few days ago (July 2010). The source is 5,822 lines of Apple Pascal and 3,583 lines of 68000 assembly.
A brief history of MacPaint can be viewed on the museum’s website www.computerhistory.org/highlights/macpaint/.

He Sold His Share For What?!?By Michael Duplessis Found in Kibbles & Bytes #790
.... In 1976 Mr. Wayne, who worked at Atari with Steve Jobs, helped found Apple Computers. He drew the first Apple logo, wrote the original partnership agreement, and wrote the Apple I manual. For his assistance, he was awarded a 10% stake in the company. Less than two weeks later, he sold his share back to Jobs and Steve Wozniak for $800 as he was worried that the new company would go into debt and he had assets that creditors could potentially seize.
This week (Aug 2012), Apple became the most valuable company of all time (not adjusting for inflation because if you do Microsoft is still the winner and no one wants that) hitting a total market capitalization of around 624 billion dollars. This would make Wayne’s share 62.4 billion dollars, which is 78 million times as much as he was paid for it.
For all of you out there who rue not buying Apple stock when it was under $10, take some comfort in the fact that you only lost out on multiplying your investment 100 times or so. That is nothing compared to a 62.4 billion dollar error in judgment.

The oldest computer can be traced back to Adam and Eve.
Surprise! Surprise! Surprise!
It was an Apple; but with extremely limited memory.
Just 2 bytes!

Et oui, il y avait des disquettes spécialisés en 1984 !
Bien que le rendue à l'écran soit vraiment très médiocre si l'on compare a aujourd'hui.

IBM’s SAGE is a large semi-automated air defense system from the Cold War era. It would analyze radar data in real-time to identify Soviet bombers. And it has built-in cigarette lighters and ashtrays at each console. It is the subject of Puzzle 47.
Here you can see about half of the wall of vacuum tubes; the other half could not fit in the frame.
Weight: 300 tons
Cost: ~$10B
This “company-making” sale was made personally by IBM founder Tom Watson, Sr.
Built in 1954, deployed in 1958, obsolete by 1960.
The last of 27 installations was shut down in 1983 (in Canada). In the final years, to the chagrin of the USAF, replacement vacuum tubes had to be bought from Soviet bloc countries.
The software development “employed about 20% of the world’s programmers at the peak of the project. When it was complete, the 250,000 lines of code was the most complex piece of software in existence.” (Computer History Museum details)
Update from below: I just met with a former IBM exec who remembers this program well.
The debug protocol was poetic. Downtime was common. The diagnostic steps were:
1) Visualize it. With the room lights off, the active tubes could be seen glowing. A dark patch was indicative of a power rail connector problem.
2) Listen to the technology. Each of the SLT logic modules were wired through an OR gate and connected to an audio amp. So, as each logic module fired, it added to the acoustic summation. The engineers would listen to the song of the computer and could often recognize common variations.
3)Whack a Mole. If the acoustic pattern seemed erratic, out comes the rubber hammer. Each of the circuit modules would receive a hammer tap to see if the song remains the same. If it changed, then that indicated a loose connector had just been banged back into place.
A fascinating exercise in pattern recognition across the emergent melodies of complex systems...

Joystick Apple modèle : A2M2002.
C'est se joystick - mythique - qui a permis à toute une génération de "s'éclater" avec les jeux vidéo conçue pour la famille des Apple II !
L'écran qui devait transformer l'Apple IIc en portable ...
Présenté pour la première fois en France au Sicob 1984 celui-ci fut disponible auprès des concessionnaires au début 1985.
De toute petite taille, 29 cm de largeur, 13,8 de profondeur et 4 cm seulement épaisseur il était très en avance sur son époque. L'idée était de rendre l'Apple IIc transportable et utilisable n'importe où. Du temps où les portables n'existaient pas c'était un argument du poids auprès de professionnels appelés a se déplacer souvent.
Il a été conçu pour s'installer avec précision sur le dessus de l'Apple IIc et d'après la brochure publicitaire " pour s'ajuster parfaitement à l'angle optimal de vision ..."
Le gros pont positif de cet écran est son alimentation. En effet il est alimenté directement à partir de l'Apple IIc via la sortie vidéo spéciale à 15 broches (DB-15) aucun besoin d'une source électrique extérieure. Je vous rappelle que cette prise est celle qui reçoit l'adaptateur Péritélévision. Il faudra donc choisir entre l'écran plat ou un téléviseur couleur mais pas les deux à la fois. Par contre il est possible de brancher un moniteur monochrome pour bénéficier d'un second écran. Bien sur il vous faudra toujours une prise électrique pour alimenter l'unité centrale Apple IIc.
L'écran plat affiche des textes "plein écran" sur 80 caractères par ligne et 24 lignes par écran. La résolution est de 560 points horizontaux sur 152 points verticaux. Sur l'arrière de l'écran, coté gauche (voir photo) il existe un interrupteur qui permet de passer des caractères clairs sur fond sombre à des caractères sombres sur fond clair. Le but étant d'améliorer le confort de lecture. Il offre une vision "confortable" dans un angle relativement fermé d'environ 10 degrés de part et d'autre du plan vertical. Il est aussi possible de l'incliner de 0 à 45 degrés.
Concernant l'utilisation de l'écran Apple indique qu'il est indispensable que l'écran soit fortement éclairé par une source de lumière indirecte ne produisant pas de reflets sur celui-ci ... Dernier conseil ne jamais l'exposer directement aux rayons de soleil. Pour un écran qui devait pouvoir être emporté et utilisé partout cela fait beaucoup de restriction.
Il fut commercialisé sous la référence produit A2M4022Z à un tarif d'environ 8000 frs soit 1200 €. Tarif qui me semble raisonnable pour l'époque si l'écran avait tenue toute ses promesses.
En fait se fut un flop commercial. Le gros, très gros problème de l'écran était sa lisibilité vraiment médiocre et je suis gentil quand j'utilise le terme de médiocre. Soyons clair, l'écran n'était pas utilisable sauf dans des conditions optimales difficilement trouvables et malgré ses conditions il vous garantissait un mal de tête au bout 1/2 heure d'utilisation. De nos jours, l'écran ayant été fabriqué à peu d'exemplaires il est un objet de choix, difficile à trouver, pour tout collectionneur.

Sometimes parodied outside the company, the classic IBM “THINK” sign was a feature in many IBM offices from the 1920s to the 1970s. The "THINK" concept, reflecting the company mantra of individual initiative, originated by IBM founder Thomas J. Watson, Sr.

Stereo equipment designers have exploited this innate attraction for years. =)
And in this full size photo, you can appreciate IBM’s pinnacle of geek bling-bling – an immersive widescreen of blinky bliss.
This IBM System/360 Model 91 was a scientific computer used at SLAC in 1968. It used Solid Logic Technology (modules of five to six transistors) during the transition period between discrete transistors and the IC.

Remember how Dave has to pull the rows of circuit boards to shut down HAL in 2001: A Space Odyssey…. According to the docent at CHM, this particular ILLIAC IV computer, with its unique architecture, was the inspiration to Stanley Kubrick for that scene.
In this SIMD parallel computing machine, each board has a fixed program that it would farm out to an array of Burroughs machines. It was the “cutting edge” in 1966.
This is how Greater Manchester Police’s computer technology looked back in 1986.
This image was taken in the Force’s newly opened communications and computer centre at the Force’s headquarters in Stretford.
At t the time the building was considered to be the most advanced of its type in policing.
The building is still in use to this day…but the technology has moved on.

Another shot from our trip to the Computer History Museum. This is the Hollerith Census Machine.
From the display;
"Herman Hollerith invented the first automated tabulating system using punch cards. Initially designed to process the 1890 US census, his system became the basis for punch card accounting machines for most of the twentieth century. Hollerith became wealthy as his Tabulating Machine Company expanded beyond government customers to include railroads, insurance companies, and manufacturers.
Hollerith sold his patent rights in 1911 to a holding company that was renamed International Business Machines Corporation (IBM) in 1924. Throughout most of the 20th century, punch card machines grew very sophistocated and bridged the gap between paper and electronic ages."
US population counted in the 1890 census was right around 63 million. Today we're at 306 million and counting.

Plus qu'un micro, une véritable oeuvre d'art. Il intégrait tout ce qui se faisait de mieux pour l'époque.
Sortie en 1997, il fut construit à très peu d'exemplaires puis les moules détruits pour toujours... 600 ont été vendus en France et 3000 en Europe.
