Expansion Bus Connector Pinouts

Tables 2–34 through 2–37 show the pinout and signal functions on the PC/104-compliant expansion bus connectors. The expansion bus pin numbers shown in the following tables correspond to the scheme normally used on ISA expansion bus card sockets. Rather than numerical designations (1, 2, 3) they have alphanumeric designations (A1, A2…, B1, B2…, etc.).

The Little Board/486e CPU does not generate ±12VDC or -5VDC for the expansion bus. If devices on the bus require these voltages, they can be supplied to the bus connector from the Power Connector (J7).
