I started one years ago and have been working on it very slowly as a 
background project.
I used small, modern relays as they can be bought in quantity cheaply. I 
paid less than
5 cents each for mine. I've built memory out of the relays and have been 
toying with using
a flip-dot type display board as a visual memory. A kind of mechanical 
graphical display.
