 In the original system, the Menehune forwarded correctly received user data to the UH central computer, an IBM System 360/65 time-sharing system.Outgoing messages from the 360 were converted into packets by the Menehune, which were queued and broadcast to the remote users at a data rate of 9600 bit/s.Unlike the half-duplex radios at the user TCUs, the Menehune was interfaced to the radio channels with full-duplex radio equipment.
