operation of a system.
As shown in Fig. 1, a printed-circuit card 1 has a plug receptacle 3 mounted
at the lower edge thereof. Signal and power lines on the rear of the board extend
from the receptacle 3 to a plurality of packaged logic inverters 5, as well as to a
plurality of settable switches, such as A, B, C, which may be either conventional
switches, such as miniature toggle switches, or combinations of sockets and
jumper connections. One or more solid state segmented displays 7 are located
