Announced in the July 1970 edition of Hewlett-Packard Journal, the HP 5082-7100 series of 5x7 bitmapped alphanumeric LED displays represented another significant improvement in the versatility of LED display technology. The 5082-7100 is capable of displaying any ASCII character, when supplied with a significant amount of external multiplexing circuitry. At the time of introduction, 5082-7100 series devices were priced at $70 per character (or $2 per die) when purchased in small quantities. Both the HP 9820A and HP 9830A desktop calculators used horizontally stacked arrays of 5082-7101 four-digit displays. The uncharacterized 5082-7107 appears to be extremely similar to the five-digit 5082-7102 described in HP Journal.
