that year, the popularity of Nature-Tand's products had begun to slide. Charles Tandy died on November 4, 1978, at the age of 60. Concurrently, key stakeholders began to question the direction of the company. Wray Thompson subsequently resigned from his position as president and later started The Leather Factory with Ron Morgan, which eventually purchased Tandy Leather Corporation in 2000. Computers Tandy was one of three companies (along with Commodore International and Apple) that started the personal computer revolution in 1977 by introducing complete pre-assembled microcomputers instead of a kit. Their TRS-80 (1977) and TRS-80 Color Computer ("CoCo") (1980) line of home computers were popular in the years before the IBM PC became commonplace, and had wide distribution in Radio Shack stores at a time when there were few computer stores. By 1981, computers were the most important part of Tandy's sales. The company attempted to monopolize software and peripheral sales by keeping technical information secret and not selling third-party products in Tandy-owned stores. An experimental Tandy computer store at company headquarters sold non-Tandy products until the company banned doing so. A market research company reported in 1981 that not selling others' products slowed Tandy's growth, and predicted that competitors would benefit. Discussing the report, Wayne Green, publisher of 80 Microcomputing, warned that the company might have become overconfident from defeating "poorly financed and inadequately managed competitors", and that IBM and others would not likely be "as myopic and hidebound as Radio Shack". He wrote that had Tandy continued its experiment, "they might have a couple of thousand Tandy Computer Centers around the country, instead of the Byte Shops and Computerlands we now see. And Tandy would have had a lot more control over Apple and other upstarts". In 1982 he wrote that while its thousands of stores were once a "considerable advantage" over competitors, "The Shack is falling way behind in sales outlets and thus in sales ... we've seen the Apple come along and, with fewer outlets, pass the TRS-80 by in sales". Green warned that the company needed to make "soul-searching, perhaps painful, decisions". Tandy's market share—as high as 60% at one time—indeed declined by 1983 because of competition from the IBM PC and lack of third-party products. Tandy adopted the IBM PC compatible architecture with the Tandy 1000 and Tandy 2000 (1983–1984). The 1000 helped Tandy achieve a 25% personal-computer market share in 1986, tied with
