The five power rails on the Prototyping Board each supply +15 V , 15 V,
+5 V, and ground. A small section of the Prototyping Board (next to
header H106) has labels indicating the repeating sequence of the voltages.
Figure C-3 shows the power rails.

The pads on the Prototyping Board have various diameters. All the pads
along a power rail have a 60-mil outer diameter and a 37-mil inner diame-
ter. Most other pads are 65/45, except the three columns of pads nearest
the ICL7662 converter, which have pads that have an outer diameter of
70mil and an inner diameter of 50 mil. These larger pads are ideal for
components, such as diodes, with thicker legs.
Note that all ground pins have square pads on the power rails.
