Announced in the February 1969 edition of Hewlett-Packard Journal, the 5082-7000 Solid State Numeric Indicator was the world's first intelligent LED display. HP touted the 5082-7000 as being the culmination of six years of LED research and development, combined with their experience in semiconductor production and optoelectronic packaging. The single digit 5082-7000 and three digit 5082-7001 accept ASCII-conforming 8-4-2-1 BCD input, and are TTL compatible. This basic configuration would later be replicated in dozens of other similar devices.

Although apparently primitive compared to its innumerable descendants, the 5082-7000 was a total revolution in digital display technology. Its direct descendants, the 5082-7340 and competing Texas Instruments TIL311, would come to dominate the intelligent display industry through the 1970s and 1980s. Burroughs Corporation, who had enjoyed a near monopoly for over a decade with various Nixie-based products, would be driven out of the market entirely. Additionally, the technology used in the 5082-7000 was adapted by Hamilton Watch Company, in the development of their Pulsar LED wristwatch.
