Dragon Data Ltd operated in the early 1980s, producing 32KB and 64KB home computers. The business was set up by a toy company, Mettoy, and initial sales were strong. A magazine, 'Dragon User' was set-up shortly after the microcomputer was launched. The technical limitations of the products led to a loss of market share. The company came under the control of GEC (the General Electric Company), and developed the Dragon Alpha (or Professional) and Beta (or 128). The new systems made it to the prototype stage before the business went into receivership. The company was sold to the Spanish startup Eurohard in 1984. It was under Eurohard that the Dragon 200 was released. Eurohard itself experienced financial difficulties and filed for bankruptcy in 1987.
