 Each packet consisted of a 32-bit header and a 16-bit header parity check word, followed by up to 80 bytes of data and a 16-bit parity check word for the data.The header contained address information identifying a particular user so that when the Menehune broadcast a packet, only the intended user's node would accept it.The central node communications processor was an HP 2100 minicomputer called the Menehune, which is the Hawaiian language word for "imp", or dwarf people, and was named for its similar role to the original ARPANET Interface Message Processor (IMP) which was being deployed at about the same time.
