Overview
Sun Remarketing was a United States retail and computer-reselling company founded by Robert L. "Bob" Cook in 1979. The business originally operated as Cook's, Inc. and adopted the Sun Remarketing name in 1983. It built its identity around finding commercial uses and resale markets for discontinued, surplus, used, and damaged Apple computer equipment at a time when personal-computer product cycles were moving quickly and manufacturers were abandoning older systems. The company's best-known business was its work with the Apple Lisa. After Apple Computer discontinued the Lisa in September 1985, Sun Remarketing purchased between 5,000 and 7,000 unsold machines from Apple. During the same period, it acquired approximately 3,500 unsold Apple III computers as well as thousands of used and broken Lisa units from nearby businesses. Rather than simply liquidating the inventory, Sun refurbished and upgraded many of the computers. Lisa systems were fitted with 800-KB 3.5-inch floppy-disk drives and 20-MB hard drives, improvements that made the machines more practical for contemporary users and helped extend the commercial life of hardware that Apple had ceased to promote. Sun also pursued software-based solutions to the Lisa's compatibility problem. It acquired Apple's MacWorks XL emulator and used it to allow Lisa computers to run Macintosh applications. When Apple's Macintosh Plus introduced an enhanced 128K ROM and newer Macintosh software became incompatible with MacWorks XL, Sun sponsored development of a successor emulator, MacWorks Plus. The company packaged the upgraded emulator and modified Lisa hardware as the Lisa Professional, positioning the product as a more capable and affordable way to access Macintosh software without purchasing a new Macintosh system. The company broadened its resale activity in 1988, when it began selling Apple Macintosh models such as the Macintosh Plus, Macintosh SE, and Macintosh II. Its business therefore evolved from a specialist outlet for discontinued Apple systems into a broader Apple-oriented reseller and refurbisher. Sun's activities included hardware resale, upgrades, software distribution, technical documentation, and the development or publication of materials supporting legacy Apple equipment. Its catalogues and do-it-yourself guides became part of the historical record of the Lisa and Macintosh aftermarket. Sun Remarketing was also known locally in Cache Valley as one of the first commercial Internet service providers in northern Utah. This added an early online-services role to a company otherwise primarily associated with computer retailing and legacy-hardware support. The company was bought out by Cherokee Data, an Oklahoma computer wholesaler, in 2006. Public reference material does not establish a continuing Sun Remarketing operation after that transaction. A later company called Cherokee Data Solutions, also known as CDS, is described as unrelated and unaffiliated with Cherokee Data or Sun Remarketing.
History
Sun Remarketing began in 1979 under founder Robert L. "Bob" Cook. The company was originally named Cook's, Inc. and changed its name to Sun Remarketing in 1983. Its central business was the resale of older Apple hardware and software, serving customers interested in systems that Apple had discontinued or no longer actively supported. The company's historical importance is closely associated with the Apple Lisa. Apple discontinued the Lisa in September 1985, leaving a substantial amount of unsold inventory. Sun Remarketing purchased an estimated 5,000 to 7,000 unsold Lisas from Apple. It also obtained roughly 3,500 unsold Apple III computers and thousands of used or damaged Lisa systems from businesses in the surrounding area. The company refurbished and modernized some of this equipment rather than treating it solely as obsolete stock. Upgrades included 800-KB 3.5-inch floppy drives and 20-MB hard drives, which improved storage and media compatibility. Sun's Lisa strategy also depended on software compatibility. The company bought the MacWorks XL emulator from Apple, allowing Lisa computers to run Macintosh applications. The arrival of the Macintosh Plus created a problem because its enhanced 128K ROM enabled newer software that did not work properly with MacWorks XL. To address this limitation and help sell its remaining Lisa inventory, Sun Remarketing underwrote development of MacWorks Plus. The company combined the newer emulator with modified Lisa hardware and marketed the result as the Lisa Professional. The Lisa resale effort continued through the late 1980s, with Sun selling thousands of consigned systems between 1985 and 1989. In September 1989, Apple reclaimed approximately 2,700 remaining Lisas stored in Sun's warehouse and disposed of them at a landfill in Logan, Utah. This episode later became associated with the broader historical story of the Lisa's commercial failure and Apple's disposal of unsold machines. Sun expanded its activities in 1988 by reselling Macintosh computers, including the Macintosh Plus, Macintosh SE, and Macintosh II. This represented a move from a narrow focus on the Lisa and earlier Apple systems toward a wider Apple resale business. The company also produced or distributed supporting materials, including a catalogue and a Lisa/Macintosh XL do-it-yourself guide, helping users maintain and adapt aging equipment. In addition to computer resale, Sun Remarketing became known locally in Cache Valley as one of the first commercial Internet service providers in northern Utah. The available account does not provide detailed dates, product names, subscriber figures, or financial information for this service. In 2006, Cherokee Data, a computer wholesaler based in Oklahoma, bought Sun Remarketing. Reference material does not document a continuing independent Sun Remarketing business after the buyout. A company called Cherokee Data Solutions, also known as CDS, is specifically described as unrelated and unaffiliated with Cherokee Data and Sun Remarketing.
