Table 2-2 describes the connectors shown in Figure 2-6. All I/O connectors use 0.100" pin (2.54mm)
spacing unless otherwise indicated.

NOTE
Ampro uses a connector/header identification method in Chapter 3 to
avoid difficult to see visible numbering next to the connectors. For
example, a 20-pin header with two rows of pins, using odd/even
numbering, where pin-2 is directly across and adjacent to pin-1, is noted
in this way; 20-pin, two rows, odd/even (1, 2). Alternately, a 20-pin
connector using consecutive numbering, where pin-11 is directly across
and adjacent to pin-1, is noted in this way; 20-pin, two rows, consecutive
(1, 11). The second number in the parenthesis is always directly across
from and adjacent to pin-1, with a few exceptions (DIMM1 slot,
PC/104-Plus, PC/104). See Figure 2-5.
