PortSavers protect the wear and tear of computer ports! Notebook computer ports are impossible to repair if worn out as a result of constant plugging and unplugging of cables and peripherals. A PortSaver is inexpensive and can be easily discarded and replaced. This slim adaptor attaches securely and works with any DB15 connections including game, joystick, MIDI, AUI, X.21 or on a Macintosh video port. (Connectors: DB15 Male to Female)
