Overview
The Keyboard Company, Inc. was an American electronics manufacturer based in Garden Grove, California, best known for producing keyboards and accessories for Apple Computer during the formative years of the Apple II and Apple III. Although the company existed as a legally separate corporation, it became closely integrated with Apple’s hardware supply chain soon after its creation and was ultimately purchased outright by Apple in 1982. The company was founded by Michael Muller, a former general manager of Datanetics, a Fountain Valley manufacturer of keyboards for calculators, cash registers, and early computer systems. Datanetics had been acquired by International Telephone & Telegraph in 1976. In 1977, Steve Jobs commissioned Datanetics to manufacture keyboards for the original Apple II. As demand from Apple and other computer makers increased, Jobs encouraged Muller to establish a separate company focused on Apple keyboard production. The Keyboard Company was incorporated on May 4, 1979, and by September of that year it was functioning as a wholly owned Apple manufacturing subsidiary in practical terms, despite remaining legally distinct. Its Garden Grove facility became an important production site for Apple II keyboard units. The plant reportedly reached output of approximately 50,000 units per month. The company’s principal business was contract manufacturing, but it also developed and sold peripherals for Apple systems. Its first notable independent product was an external numeric keypad for the Apple II, introduced around late 1979 or early 1980. The keypad addressed a limitation of the original Apple II, which lacked a dedicated numeric section, and was particularly relevant to accounting users and owners of VisiCalc, the influential spreadsheet program. Its installation used a daughterboard and ribbon-cable connections rather than requiring soldering. Apple commissioned the company to manufacture Apple III keyboards in spring 1980. As Apple’s user base expanded beyond business applications into entertainment and gaming, The Keyboard Company broadened its accessory range. It introduced the Joystick II for the Apple II and Cursor III for the Apple III in 1981, followed by Hand Controllers, a pair of paddle-style controllers, in 1982. On April 1, 1982, Apple purchased The Keyboard Company and its Garden Grove facility. The operation was renamed the Accessory Products Division, commonly abbreviated APD, and Muller became its president and general manager. Under Apple ownership, the organization expanded beyond keyboard manufacturing and contributed to the development and production of printers, including the LaserWriter and ImageWriter families. In Apple’s 1984 organizational structure, APD operated as a separate business unit alongside the Apple II and Apple 32 divisions, the latter covering Lisa and Macintosh development and production. Muller later established an APD factory in Millstreet, County Cork, Ireland, and remained with Apple until 1987. The Garden Grove workforce reached 661 employees in February 1985, but layoffs later that year reduced employment to 275. Alps Electric announced an acquisition of the Garden Grove plant in August 1985, with the transaction completed on August 28. The facility subsequently manufactured Apple mice under Alps ownership. Alps eventually announced the site’s closure in the late 1990s, and the plant shut down in spring 1998. The Keyboard Company therefore survives primarily as an important early Apple manufacturing and peripheral-supply business rather than as an active standalone brand.
History
The Keyboard Company emerged from the Southern California electronics-manufacturing network surrounding Datanetics. Michael Muller had served as Datanetics' general manager before International Telephone & Telegraph acquired that company in 1976. Datanetics manufactured keyboards for electronic calculators and cash registers and became an early supplier to computer makers. In spring 1977, Steve Jobs engaged Datanetics to manufacture keyboards for the original Apple II. The supplier subsequently received work from other manufacturers, including Mattel Electronics. Jobs later encouraged Muller to form an independent company dedicated to Apple keyboard production. The Keyboard Company was incorporated on May 4, 1979. By September 1979, it was operating from a Garden Grove plant and carrying out Apple II keyboard manufacturing, while maintaining a separate legal identity. The operation quickly became a substantial production resource for Apple, reaching an output of about 50,000 keyboard units per month. The company also pursued its own peripheral products. Around the end of 1979 or the beginning of 1980, it introduced an external numeric keypad for the Apple II. The product was aimed in part at accounting users, an important early Apple II market, and addressed the absence of a dedicated numeric keypad on the original computer. Its design used an internal daughterboard and ribbon-cable connections, allowing installation without soldering. The accessory gained attention among VisiCalc users. In spring 1980, Apple selected The Keyboard Company to manufacture keyboards for the Apple III. The company then expanded into input devices associated with gaming and interactive software. The Joystick II was made for the Apple II and the Cursor III for the Apple III in 1981. In 1982, it introduced Hand Controllers, paddle controllers sold as a pair. Apple acquired The Keyboard Company and its Garden Grove facility on April 1, 1982. The former company became Apple's Accessory Products Division, or APD, with Muller appointed president and general manager. APD's responsibilities broadened considerably under Apple ownership. Muller promoted the development of printers using different technologies, work that led to products such as the LaserWriter and ImageWriter. In 1984, Apple organized its operations into three business units: Apple II, Apple 32, and APD. APD was responsible for accessory activities and continued under Muller's leadership. Muller opened an APD manufacturing facility in Millstreet, County Cork, Ireland, and left Apple in 1987. The Garden Grove factory remained a significant employer, with 661 workers recorded in February 1985. Mid-1985 layoffs reduced the workforce to 275. In August, Alps Electric of Tokyo announced plans to acquire the site from Apple while retaining the remaining employees; the transaction closed on August 28, 1985. The former Keyboard Company facility continued under Alps ownership. By the late 1990s, it employed about 500 people and concentrated on producing mice for Apple. Alps later issued employees notices ranging from six months to one year before the plant's closure, with many receiving retention bonuses. The factory finally shut down in spring 1998. The Keyboard Company itself ceased to exist as an independent business after Apple's 1982 acquisition, but its manufacturing lineage continued through APD and later the Alps-operated facility.
