We forget about all of the alternative ways of implementing digital logic. At one time, magnetic core logic was viewed as being much more reliable than either tube or transistor logic, although not as fast. Probably better hardened to radiation, as well. In some respects, core logic reminds me somewhat of the McCulloch-Pitts TLU model described in Minsky's book on Computation: http://www.i-programmer.info/babbages-bag/325-mcculloch-pitts-neural-networks.html --Chuck
