Lamp Driver:
A 3-to-8 latching demuxer is connected to the input bits.
A 3-to-8 latching demuxer (MC14099) is connected to the input bits.
Three of the inputs (J1-11,10,12) specify which output to write
to, and the fourth input (J1-14) is the data value. A fifth input
(J1-13) controls the strobe to latch the data value for the
demuxer. The eight outputs directly control 8 lamps.
