TEXT -520 -288 Left 0 ;9:3 multiplexer\nSelect from one of three groups of 3 trits
TEXT -848 -104 Left 0 ;Note: this is inefficient; the 1:3 decoder circuitry is redundant in each\nof the 3:1 multiplexers. For efficiency, this circuit should be made from\na 1:3 decoder and 3 groups of 3 transmission gates. See alu.asc for\nan example of how to do this.
