Description
Gateway 955 CD-Rom/Floppy Combo Drive For Notebook Computers. The combination drive module contains a slimline CD-ROM drive and a slimline floppy disk drive. They are mounted on a common drive tray. Adapter boards for converting the connections to the standard IDE and floppy connections are mounted on the board as well. The slimline floppy peripheral connection is a short length of Flexible Circuit, the power connector is a right angle four-position header and the cable interface is a standard vertical floppy header (with pin 3 pulled). One 6-32 screw is used to secure this board.
