Claim One:
1. Electronic computing apparatus comprising (a) a multiplicity of amplifier means, each one of the amplifier means having at least one input terminal and at least one output terminal; (b) means for electrically connecting the output terminal of any given amplifier means A.sub.j to the input terminal of at least one other amplifier means A.sub.i, the electrical connection having a predetermined resistance; (c) means for applying an electrical signal at least to the input terminal of one of the amplifier means; and (d) means that are responsive to the output signal of at least one of the amplifier means; characterized in that (e) the means of (b) comprise a programmable resistor body consisting substantially of a material having a state of relatively high resistivity and having a first and second major surface, a portion S.sub.i of the first surface being associated with A.sub.i and a portion S.sub.j of the second surface being associated with A.sub.j, associated with the programmable resistor body is a resistance R.sub.ij between S.sub.i and S.sub.j, the value of R.sub.ij being changeable from a relatively high value associated with the state of relatively high resistivity to a lower value by application of a "write" voltage between S.sub.i and S.sub.j, and the value of R.sub.ij being furthermore changeable from the lower value to a higher value by application of an "erase" voltage between S.sub.i and S.sub.j ; and (f) the apparatus further comprises means for applying the "write" voltage and the "erase" voltage between S.sub.i and S.sub.j, such that a predetermined resistance R.sub.ij can be formed between S.sub.i and S.sub.j, and such that the electrical connection of predetermined resistance between the input terminal of A.sub.i and the output terminal of A.sub.j is established.
