REPLACEABLE PARTS
Table 5 -1 provides a list of replaceable parts for the iSBC
80/30. Table 5-2 identifies and locates the manufacturers
specified in the MFR CODE column in table 5 -1. Intel
parts that are available on the open market are listed in the
MFR CODE column as "COML"; every effort should be
made to procure these parts from a local (commercial)
distributor.
5-3. SERVICE DIAGRAMS
The iSBC 80/30 parts location diagram and schematic
diagram are provided in figures 5-1 and 5-2, respectively.
On the schematic diagram, a signal mnemonic that ends
with a slash (e.g., 10WC/) is active low. Conversely, a
signal mnemonic without a slash (e.g., BTMO) is active
high.
