I believe that in nearly all cases combinations of two state flip flops (not the sandal the bistable tube), then magnetic cores having only two directions of magnetization, and so on, were used, never an n- state device where n is an integer > 2, nor an analogue device where n is Cantorian aleph 1. Except perhaps in hybrid analogue computers but in these the existence of "memory" is hard to separate from "nature". > > -- > Bartc
