An improved mail sorting computer keyboard, having a plurality of keys arranged in first and second groups for rotational movement, is provided. A first rod is disposed through apertures of each key of the first group of keys while a second rod is disposed through apertures of each key the second group of keys. A third rod extending transversely across the keyboard and under a front portion of the first group of keys and a fourth rod extending above the first group of keys define the rotational arch for the first group of keys. A fifth rod transversely disposed under a front portion of the second group of keys and a sixth rod transversely disposed under the rearward portion of the second group of keys defines the rotational arch for the second group of keys. Each key of the keyboard actuates a corresponding electrical switch for sending impulses to a mail sorting computer. The mail sorting computer keyboard also includes a circuit for translating coordinates denoting a particular key into the corresponding coordinates of a key of any other computer with which it may be desired to interface the mail sorting computer keyboard.
