2U PCI/AGP 3 in 1 Right Angle Riser 64-bit PCI PCI/AGP-PRO/PCI, 3 in 1 right angle riser. The overall dimension of the main board assembly is 2.95"H x 7.00"W. The middle AGP-PRO connector is connected directly to the AGP-PRO gold fingers. The top connector is connected to the bottom connector. However, there are some dedicated signals that are borrowed from a small paddle board which is plugged into an adjacent slot. The bottom connector is a completely independent connection, coming from a separate paddle board of another PCI slot on the motherboard. The user can order the riser with PCI-32 bit or PCI 64 bit connectors and AGP or AGP-PRO connector. All connectors are mounted on the B side of the riser card. This riser is designed to plug into an AGP or an AGP-PRO slot on the motherboard. The high performance kapton cable is 3" long and it supports higher PCI bus speed. Picture shown here is populated with 2 PCI-64 bit 3.3V connectors, and a AGP-PRO universal connector. The top PCI connector is located at 2.571", the center AGP connector is located at 1.771", and the bottom PCI connector is located at 0.971" from the bottom of the board. MB PCI/AGP Slot positions: Position A: normally it s AGP, 6.4" away from the Keyboard connector edge. Position B: normally it s 1st PCI, 7.2" away from the Keyboard connector edge. Position C: normally it s 2nd PCI slot. Position D: normally it s 3rd PCI slot.
