ArcadeVGA AGP cards, 1x version 1 and 3x version 2 (with DVI-I out). Version 1 card top right.
Extra holes on the round svideo output suggest component video output, which is supported with the Radeon 9250 chipset ArcadeVGA is based on. The two cards on the right have this (version 1 and red version 2). Two cards on the left do not.
