Interdata Computer boards ?

Intedata was a computer mfg. They made a series of machines (I vaguely
remember a model 4.) They were somewhat like a 360/30, I seem to recall.
Their chief claim to fame was that they were designed to be
microprogrammable. I think one of the implementations used a set of wires
strung through a series of W-shaped transformers. Passing the wire through 1
side resulted in a 0, and the other side gave a 1. Thus it was possible to
change the microprogram and thus extend the instruction set of the computer.
