8. Insert eight 1 kohm resistors (R15–R18, R32–R35) from the emitter
   pins of each transistor to the ground bus, as shown in Figure 5-11.


9. Insert one 2.2 kohm resistor (R1), one 2 kohm resistor (R2), two 47
   kohm resistors (R3 and R4), one 100 kohm resistor (R5), two 5 kohm
   resistors (R6 and R8), one 1 kohm resistor (R9), one 5 kohm resistor
   (R6), and one 220 kohm resistor (R10) on the breadboard, as shown in
   Figure 5-12.
