The connector consists of two rows of pins labeled A and B, the numbering of of which is shown below. Most of the pins on the PC104 bus are only 3.3V tolerant.

You can also drive these DIO to manually manipulate the PC104 address to make peripherals usable that require a higher range of address than provided by the default address space of the MUXBUS.
