Released September 8, 1998, AMR is short for Audio/Modem Riser and allows OEMs to make one card that has the functionality of either Modem or Audio or both Audio and Modem on one card. This specification allows for the motherboard to be manufactured at a lower cost and free up industry standard expansion slots in the system for other additional plug-in peripherals. The picture an example of what the AMR slot looks like on the Motherboard. This slot is often on the far edge of the motherboard, next to a PCI slot.

With more modems and sound cards being integrated into the motherboard, more people using broadband and no longer needing a modem, and better technologies like PCIe, AMR never gained mass adoption. Today, AMR is no longer found or used with any modern motherboard.
