PC/104-Plus Bus Interface
The PC/104-Plus bus is a modification of the standard PCI bus. It allows all of the PC/104 features to be used,
together with the high speed PCI bus.
The main features are:
 PC/104-Plus Bus slot, fully compatible with PCI version 2.2 specifications.
 Integrated PCI arbitration interface (32 bit wide, 3.3V).
 Translation of PCI cycles to ISA bus.
 Translation of ISA master initiated cycle to PCI.
 Support for burst read/write from PCI master.
 33 MHz PCI clock.
 Power: +3.3V, +5V, +12V, -12V
Note: The 3.3V pins on the PC/104 Plus bus are not supplied by the onboard
3.3V power supply in default. The maximum current is limited to 10.0 A.
With 0R0-Resistor-Jumpers the 3.3V pins can by supplied by the
onboard 3.3V power supply, but with a lower current limit.
If a PC/104-Plus peripheral board needs 3.3V supply from the bus with
more than that limit, it must be supplied externally.
