I have an interest in "alternative" logic gates, as in not silicon transistors. I have built RAM in a little game called "Powder Game", constructed "one-off" logic gates out of exploding lattices of popsicle sticks, and used electromechanical devices such as motors and relays. Right now, I'm intensely interested in magnetic cores. I would like to somehow experiment with these myself, but short of purchasing the equipment to do so, I haven't found a way. I am hoping that there is, perhaps, a free piece of software that would let me experiment with trying to make logic with magnetic cores. Can anybody help me find one?
Here is a PDF to describe what I am talking about: http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=04051986
