An HP 9830 system with an integrated hard drive was also provided by HP in the early 1970s to National Real Estate Exchange, Inc., a small company in Florida, for its use in developing early real estate software. The U.S. Coast Guard devised a teletype message-forwarding system based on 9825As which were deployed as a working prototype for a subsequent purpose-built system, and also used them in the coordination of LORAN radionavigation transmitter chains. HP9825s were used in conjunction with Oscor software to score one-design yachting regattas in remote locations, such as the 1976 World Fireball championships in Nova Scotia, the World
