I took it over the code base at some point and among other things added macros so that repeated wire to chip connection patterns and names could be generated without the labor intensive one wire at a time e.g. wire[0-7] connects to pin[0-7].=C2=A0 The macro would be expanded so that wire0 connected to pin0 etc.=C2=A0 This later syst= em was call UCDS - = Unix Circuit Design System.=

UCDS was used by Joe Condon for the chess machine that he and Ken built.=C2=A0 Ken may remember more about this.=C2=A0 It was also on= e of the reasons that BTL got a $1B Navy contract.
