The features essential for a personal computer were first encompassed by the Apple I: a fully-assembled circuit board with dynamic RAM, video interface, keyboard, mass storage and a high-level programming language. This affordable computer platform triggered a software industry that grew as the sophistication of these essential features grew, and the Apple I thus helped launch the personal computer revolution. In what IEEE section(s) will the milestone plaque(s) reside? Santa Clara Valley Please specify the IEEE Organizational Unit(s) which have agreed to sponsor the Milestone, and supply name and contact information for the senior officer from those OU(s). Sponsorship has three aspects: 1) Payment for the cost of the plaque(s), 2) Arranging the dedication ceremony, and 3) agreeing to monitor the plaque and to let IEEE History Center staff know in case the plaque needs to be moved, is no longer secure, etc. Number 3 must be done by the IEEE Section(s) in which the plaque(s) is located, but aspects 1 and 2 can be done by any IEEE Organizational Unit, and they need not be the same one.

Please include coordinates in decimal format rather than degrees. In the vicinity of the main entrance or the main lobby of the headquarters of Apple, Inc., at 1 Infinite Loop, Cupertino, CA 95014. What is the intended site(s) of the milestone plaque(s) relation to the achievement? The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque. Also, please Describe briefly the intended site(s) of the milestone plaque(s). (e.g. Is it corporate buildings? Historic Site? Residential? Are there other historical markers already at the site?) The current headquarters of Apple, Inc., is a high profile location in Silicon Valley. It has a direct lineage to the work done by Steve Wozniak, Steve Jobs and the team that worked on the Apple I. It is a location that is seen by and visited by thousands of visitors, vendors and Apple employees on a daily basis. Are the original buildings extant? The first Apple I prototype was designed and built by Steve Wozniak in his apartment and in his cubicle at Hewlett-Packard Co. (where he was employed at the time). Both of these were in Cupertino, CA. The apartment complex has been razed, and the Hewlett-Packard building will soon be razed in preparation for building Apple's new headquarters. Steve Jobs' house and garage at 2066 Crist Drive in Los Altos, CA, was where many of the Apple I PC boards were stuffed and tested, and it served as the focal point for Apple Computer in its earliest days. This house still exists, and it is discussed in the Bruce Newman news story which is included in the Supporting Materials section below. Please provide the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. TBD, but in the vicinity of the main entrance or the main lobby of the headquarters of Apple, Inc., in Cupertino, CA. How is the intended plaque site protected/secured, and in what ways is it accessible to the public? If visitors to the plaque site will need to go through security, or make an appointment, please give details as well as the contact information visitors will need in order to arrange to visit the plaque. The main entrance and the main lobby of the headquarters of Apple, Inc., at 1 Infinite Loop, Cupertino, CA, are fully accessible to the public. Who is the present owner of the site(s)? Apple, Inc., owns all of the buildings at its headquarters. In the space below, please describe in detail: the historic significance of the achievement, its importance to the evolution of electrical and computer engineering and science, its importance to regional/national/international development, its benefits to humanity, the ways the achievement was a significant advance rather than an incremental improvement of existing technology. The material submitted here will constitute the main descriptive article on the ETHW website for readers to learn about the milestone. Space is unlimited, and detail is encouraged. Most milestones require 1000 to 1500 words of support, however there is no word limit. The article should be readable by a wide audience that includes practicing engineers, scholars of history, and the general public. Some examples of the text of good milestone articles are First Radio Astronomical Observations Using Very Long Baseline Interferometry] and G3_Facsimile International Standardization of G3 Facsimile (Do not worry about the formatting of the page, IEEE History Center Staff will do that afterwards.) What is the historical significance of the work (its technological, scientific, or social importance)? All computers before the Apple I, including hobby computers, had a front panel for entry of binary data into memory, for observing binary data in memory, and for running software. All computers after the Apple I followed its formula of startup code in ROM, keyboard input, a video display, and elimination of the front panel. The Apple I design was given away publicly at Homebrew Computer Club meetings in the San Francisco Bay Area. In a real sense, the Apple I computer was one of the first open computer architectures. The Apple I was designed, built and sold in limited numbers in 1976 for $666.66. In 2013, a working Apple I computer was sold at auction for $671,400. It is believed that there are about 50 Apple I computers left in the world.(Ref. 1) What obstacles (technical, political, geographic) needed to be overcome? Prior to the Apple I, hobbyist computers were sold as kits that included components from different companies, and were affordable only in configurations that could not easily solve real-world computer problems. Early hobby computers such as the MITS Altair 8800 were programmed with front-mounted toggle switches, and indicator lights on the front panel provided output. (Ref. 2) Separate hardware was required to allow connection to a computer terminal or teletypewriter. Due to high cost, these machines typically only had 256 to 1024 bytes of RAM. In addition, the front panel components were a considerable cost factor. A remote teletype terminal with specialized hardware cost at least $700,(Ref. 3) making this an unattractive option for cost-conscious hobbyists. Early attempts to create personal computers were based on expensive static RAM, and 4KB of this expensive memory was needed to support a higher-level language such as the BASIC interpreter written by Bill Gates. With their input and output limitations, these early computers were primarily used by computer hobbyists who were willing to dedicate a lot of effort to make them work. It was very difficult for a small business or home user to enter useful programs into, or even to play computer games on, these early computers. There was thus no inexpensive computer that could be used by a casual user, and the very concept of a computer in the home was a novelty. In addition to the need to make a computer useful to regular users, there needed to be marketing about home or “personal” computers.(Ref. 4) The Apple I computer was the first product that was sold as a single assembled piece of computer hardware that could be easily used in the home, and which was marketed as a personal computer. What features set this work apart from similar achievements? Unlike earlier hobbyist computers, the Apple I was not sold as a kit to be assembled by the user. Instead, it was a fully-assembled circuit board containing over 60 chips. To make a working computer, the user had to add a power supply transformer, ASCII keyboard and a composite video display such as a conventional TV of that time. Some users also added a case and/or a power switch. An optional board providing a tape cassette interface for program and data storage was introduced after the initial product introduction (Ref. 2) and this option allowed the BASIC (Ref. 5) interpreter to be loaded into RAM. The Apple I skipped all the expense of a front panel, which included switches, wiring and chips to support input using switches and output using lights. The Apple I used an electronic keyboard as its input device. The 4096 bytes of Dynamic RAM (DRAM) used in the Apple I was less costly than magnetic core memory used in many prior computers, and it had just been introduced at the time of the Apple I design. This DRAM was also many times less expensive than the Static RAM (SRAM) used by other low cost kits, although its need to be refreshed made its use more complex than that of SRAM. DRAM used as working memory meant that logical addresses needed to be supplied in an organized fashion. The Apple I used the video circuit timing chips, from a prior terminal design of Steve Wozniak’s. These timing chips were used for a double purpose, since they also supplied the refresh addresses.(Ref. 6) This sharing of functions saved parts, and thus reduced the overall product cost. The video output and keyboard input were accomplished through a parallel interface chip. The video memory was optimized (for cost) around dynamic shift register technology, and it could be updated with new characters at a rate of 60 Hz. All the timing was based on the NTSC color standard frequency, divided down for DRAM timing, display timing, processor clocking and more. Thus, a single timing circuit replaced many independent timing circuits that were common in prior computer designs. Together, these factors made the Apple I computer small and low cost. As Steve Wozniak considered a high-level language essential for the usefulness of the Apple I, he wrote the BASIC (Ref. 5) interpreter. Without this BASIC interpreter, the Apple I would have been useful only for hard-core computer types. With a standard high-level programming language, software could be written and then distributed and used on multiple computers. This enabled a software eco-system that would increase the usefulness of the computer to casual users. The Apple I defined the elements of a personal computer, thus making it affordable and useful for “normal” people. The cost reductions that made this possible were (1) an integrated and fully assembled working computer circuit board based on the powerful 1MHz 6502 microprocessor, (2) state-of-the-art but low-cost DRAM, (3) clever sharing of components, (4) the use of a typewriter-style keyboard to replace the front panel, and (5) NTSC output through a TV modulator to an owner's existing TV (Ref. 6). The Apple I was thus able to realize the goal of a low-cost, easy-to-use personal computer.(Ref. 7) Significant references to establish the dates, location, and importance of the achievement.
