Signals on the Expansion Bay Connector

Table 4-1 shows the signal assignments on the expansion bay connector. Signal names that begin with a slash (/) are active low.

Note

The table shows the signals in the same arrangement as the pins on the connector; that is, with pin 1 next to pin 31 and pin 30 next to pin 60.
