|  |  |  |  | The PDP-5 was innovative in replacing the radial structure of earlier designs with an I/O bus. By allowing peripheral equipment to be added incrementally -- rather than preallocating space, wiring and cable drivers -- the I/O bus design lowered the base costs of the system and simplified the configuring of machines in the field.
