Its predecessor, the System 19, was introduced in September 1978. The original UniPak was introduced in 1980 and UniPak 2 in January 1983. Over 10,000 of the systems were sold. Data I/O annual reports give the sales of the Model 29 and UniPak as $18 million in 1983 and $28 million in 1985. This system cost between $5000 and $7000 depending on options (1988 price list).
