Harry T. Garland (born 1947) is a scientist, engineer, author, and entrepreneur who co-founded Cromemco Inc., one of the earliest and most successful microcomputer companies. He received the B.A. degree in mathematics from Kalamazoo College, and the Ph.D. degree in biophysics from Stanford University. [1] Dr. Garland has been recognized as one of the most important innovators in the development of personal computers in Silicon Valley. [2]
He is the son of Harry G. Garland, the founder of Garland Manufacturing.
Garland began his graduate work at Stanford University in 1968. Garland's research at Stanford focused on the function of the human brain in controlling voluntary movement. [3] He developed techniques in electromyography for monitoring muscle activity during voluntary movement [4] and worked to delineate the role of the brain and the role of local reflexes in the control of muscles. [5] This led to a deeper understanding of brain function during voluntary movement, and insight into the mode of action of L-DOPA in the treatment of Parkinson's disease. [6]
Garland received the doctoral degree from Stanford in 1972. [7] He was invited by John G. Linvill to join the research staff of the Stanford Electronics Laboratories where he worked on the Optacon project and developed the concept for the next generation Optacon reading aid for the blind. [8] In 1974, he was appointed Assistant Chairman of the Department of Electrical Engineering at Stanford University; he taught graduate courses in electrical engineering and published a textbook in the new field of microprocessor system design. [9]
While at Stanford University, Dr. Garland also worked to bring electronics technology to a wider audience. Over a period of six years, in collaboration with Stanford colleague Roger Melen, he wrote a series of articles for Popular Electronics magazine describing original designs that could be built by the electronic hobbyist. [10] [11] [12] [13] [14] During this period, Garland and Melen also published two books: Understanding IC Operational Amplifiers and Understanding CMOS Integrated Circuits. [15] [16]
The MITS Altair computer, which launched the microcomputer industry, was introduced in January 1975 issue of Popular Electronics magazine. [17] That same issue carried an article by Garland and Melen on solid-state image sensors. [18] The following month they, together with their Stanford colleague Terry Walker, published the design of the world's first completely digital solid-state camera in Popular Electronics, and began work on developing an interface to connect the camera (which they called the “Cyclops”), to the MITS Altair computer. [19] MITS introduced the Cyclops Camera as a peripheral for the Altair Computer in January 1976. [20]
Their next project for Popular Electronics was to develop an interface between the Altair computer and a color television set. They called it the “Dazzler”. Garland and Melen again collaborated with Terry Walker on the hardware design and with Ed Hall, a fellow member of the Homebrew Computer Club, on the software design. The Dazzler appeared on the front cover of the February 1976 issue of Popular Electronics, and Garland and Melen offered a kit of parts for sale. [21]
To support their sales of the Cyclops and the Dazzler, Garland and Melen rented a 200 sq. ft. office in Los Altos, California and formed Cromemco, a company named after the Stanford dormitory where they had both lived as graduate students. [22]
Dr. Garland was president of Cromemco from its incorporation in 1976 until its sale in 1987. From the original Cyclops and Dazzler products the company developed a full line of microcomputer systems that were rated as the most reliable in the industry. [23] Cromemco systems became the systems of choice for broadcast television graphics, [24] were widely deployed as Mission Planning Systems by the United States Air Force, [25] [26] and were the first microcomputer systems widely distributed in China. [27] [28]
By 1980 Cromemco occupied 200,000 sq. ft. of manufacturing and office space in Mountain View, California, and In 1981 Inc. Magazine ranked Cromemco in the top 10 fastest growing privately held companies in the U.S. [29] Garland achieved this growth without accepting any external equity financing. [30]
The success of Cromemco products in television broadcast applications was based on a successor product to the original Dazzler, called the "Super Dazzler" interface (SDI). [31] ColorGraphics Weather Systems, a customer of Cromemco, developed software for the SDI specifically for television weather graphics and digital art creation. [32] [33] Dynatech Corporation, the parent company of ColorGraphics Weather Systems, sought to acquire Cromemco to provide the computer and graphics systems for their broadcast division, and purchased Cromemco in 1987. [34]
In 1990 Dr. Garland was invited by Dr. Hajime Mitarai, president of Canon Inc., to help establish a new R&D center for Canon in Silicon Valley. [35] [36] Dr. Garland served as Vice President of this new center, Canon Research Center America, from 1990 to 2001. At Canon he developed technology for medical digital radiography equipment, and worked on standards to integrate this equipment with hospital and radiology information systems. [37] He served on the Kalamazoo College Board of Trustees from 1987 to 2005, and on the board of Industry Initiatives for Science and Math Education (IISME) from 1996 to 2010 including a term as president of that board. [38] [39] In 2002 Dr. Garland co-founded Garland Actuarial LLC with his wife, Roberta J. Garland, and serves as chairman of the firm.
Dr. Garland's contributions to the computer industry have been recognized in numerous books [1] [2] [22] [40] and on television, including appearances on the Financial News Network, [41] The Personal Computer Show, [42] The Screen Savers, [43] and in the PBS documentary Triumph of the Nerds. [44] He has received the Sesquicentennial Award from Kalamazoo College and the Distinguished Alumni Award. [45] [46] He is the author of three books: Understanding IC Operational Amplifiers, [15] Understanding CMOS Integrated Circuits, [16] and Introduction to Microprocessor System Design. [9] He has been awarded 20 U.S. Patents. [47]
The 6800 is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System that also included serial and parallel interface ICs, RAM, ROM and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year.
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive. Many microcomputers are also personal computers. An early use of the term "personal computer" in 1962 predates microprocessor-based designs. (See "Personal Computer: Computers at Companies" reference below). A "microcomputer" used as an embedded control system may have no human-readable input and output devices. "Personal computer" may be used generically or may denote an IBM PC compatible machine.
Tiny BASIC is a family of dialects of the BASIC programming language that can fit into 4 or fewer KBs of memory. Tiny BASIC was designed by Dennis Allison and the People's Computer Company (PCC) in response to the open letter published by Bill Gates complaining about users pirating Altair BASIC, which sold for $150. Tiny BASIC was intended to be a completely free version of BASIC that would run on the same early microcomputers.
Li-Chen Wang is an American computer engineer, best known for his Palo Alto Tiny BASIC for Intel 8080-based microcomputers. He was a member of the Homebrew Computer Club and made significant contributions to the software for early microcomputer systems from Tandy Corporation and Cromemco. He made early use of the word copyleft, in Palo Alto Tiny BASIC's distribution notice "@COPYLEFT ALL WRONGS RESERVED" in June 1976.
The Homebrew Computer Club was an early computer hobbyist group in Menlo Park, California, which met from March 1975 to December 1986. The club had an influential role in the development of the microcomputer revolution and the rise of that aspect of the Silicon Valley information technology industrial complex.
The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. Interest grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines. According to Harry Garland, the Altair 8800 was the product that catalyzed the microcomputer revolution of the 1970s. It was the first commercially successful personal computer. The computer bus designed for the Altair was to become a de facto standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.
The S-100 bus or Altair bus, IEEE 696-1983(inactive-withdrawn), is an early computer bus designed in 1974 as a part of the Altair 8800. The S-100 bus was the first industry standard expansion bus for the microcomputer industry. S-100 computers, consisting of processor and peripheral cards, were produced by a number of manufacturers. The S-100 bus formed the basis for homebrew computers whose builders implemented drivers for CP/M and MP/M. These S-100 microcomputers ran the gamut from hobbyist toy to small business workstation and were common in early home computers until the advent of the IBM PC.
In computing, a presentation program is a software package used to display information in the form of a slide show. It has three major functions:
Popular Electronics was an American magazine published by John August Media, LLC, and hosted at TechnicaCuriosa.com. The magazine was started by Ziff-Davis Publishing Company in October 1954 for electronics hobbyists and experimenters. It soon became the "World's Largest-Selling Electronics Magazine". In April 1957, Ziff-Davis reported an average net paid circulation of 240,151 copies. Popular Electronics was published until October 1982 when, in November 1982, Ziff-Davis launched a successor magazine, Computers & Electronics. During its last year of publication by Ziff-Davis, Popular Electronics reported an average monthly circulation of 409,344 copies. The title was sold to Gernsback Publications, and their Hands-On Electronics magazine was renamed to Popular Electronics in February 1989, and published until December 1999. The Popular Electronics trademark was then acquired by John August Media, who revived the magazine, the digital edition of which is hosted at TechnicaCuriosa.com, along with sister titles, Mechanix Illustrated and Popular Astronomy.
The Optacon is an electromechanical device that enables blind people to read printed material that has not been transcribed into Braille. The device consists of two parts: a scanner which the user runs over the material to be read, and a finger pad which translates the words into vibrations felt on the finger tips. The Optacon was conceived by John Linvill, a professor of Electrical Engineering at Stanford University, and developed with researchers at Stanford Research Institute. Telesensory Systems manufactured the device from 1971 until it was discontinued in 1996. Although effective once mastered, it was expensive and took many hours of training to reach competency. In 2005, TSI suddenly shut down. Employees were "walked out" of the building and lost accrued vacation time, medical insurance, and all benefits. Customers could not buy new machines or get existing machines fixed. Some work was done by other companies but no device with the versatility of the Optacon had been developed as of 2007. Many blind people continue to use their Optacons to this day. The Optacon offers capabilities that no other device offers including the ability to see a printed page or computer screen as it truly appears including drawings, typefaces, and specialized text layouts.
Processor Technology Corporation was a personal computer company founded in April 1975, by Gary Ingram and Bob Marsh in Berkeley, California. Their first product was a 4K byte RAM board that was compatible with the MITS Altair 8800 computer but more reliable than the MITS board. This was followed by a series of memory and I/O boards including a video display module.
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals. After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.
Cromemco, Inc. was a Mountain View, California microcomputer company known for its high-end Z80-based S-100 bus computers and peripherals in the early days of the personal computer revolution.
ColorGraphics Weather Systems was a computer graphics company that pioneered the use of computer graphics for displaying weather forecasts on local television. Formed in 1979 by Terry Kelly and Richard Daly, it is now part of Weather Central, another of Kelly's companies.
The Cromemco Dazzler was a graphics card for S-100 bus computers introduced in a Popular Electronics cover story in 1976. It was the first color graphics card available for microcomputers. The Dazzler was the first of a succession of increasingly capable graphics products from Cromemco which, by 1984, were in use at 80% of all television stations in the U.S. for the display of weather, news, and sports graphics.
Roger J. Sippl, an American entrepreneur in the computer software industry, was described in 2012 by The Wall Street Journal as a serial entrepreneur. Sippl was the founder and CEO of Informix Corporation, later becoming IBM Informix. Other sippl accomplishments included being co-founder and chairman of Vantive Corporation, and the CEO and founder of Visigenic: three companies he took public. Currently, he is the CEO of Elastic Intelligence located in Menlo Park, California.
Roger Douglas Melen (1946--2024) was an electrical engineer recognized for his early contributions to the microcomputer industry, and for his technical innovations.
The Cromemco Cyclops, introduced in 1975 by Cromemco, was the first commercial all-digital camera using a digital metal–oxide–semiconductor (MOS) image sensor. It was also the first digital camera to be interfaced to a microcomputer. The digital sensor for the camera was a modified 1 kb dynamic RAM (DRAM) memory chip that offered a resolution of 32 × 32 pixels (0.001 megapixels).
Cromemco DOS or CDOS is a CP/M-like operating system by Cromemco designed to allow users of Cromemco microcomputer systems to create and manipulate disk files using symbolic names.
The Bytesaver, introduced by Cromemco in 1976, was the first programmable memory board for the MITS Altair and S-100 bus microcomputer systems. The Bytesaver had sockets for 8 UV-erasable EPROMs providing up to 8 Kbytes of storage. The EPROMs could be programmed by the Bytesaver, or read as computer memory. In the history of microcomputer systems, the Bytesaver was the first viable alternative to the use of punched paper tape for storing programs, and has been called “a great advance in microcomputer technology”.
Dr. Garland suggested that the Optacon could be more effective if the camera and tactile screen were incorporated into a single hand-held unit.
There is little question that the current enthusiasm in personal computing was catalyzed by the introduction of the MITS Altair computer kit in January 1975.
The Altair even debuted a digital camera back in 1976.
Some 80% of all the television stations in the country use Colorgraphics's LiveLine systems to generate weather, news and sports graphics. The basic system is built around Cromemco microcomputers.
