2-21 Figure 2-3 illustrates a controller (e. g., a 9825A
calculator) and a 59501A unit connected to the HP-IB. In
this case, the 98034A interface card provides HP-IB capa¬
bility for the 9825A calculator and is installed in any one
of the three slots in the rear of the calculator. The 98034A
card is equipped with the proper cable and connector to mate
with the HP-IB connector on the rear of the 59501 A. Note
