PB 301 Motherboard Layout
Note
When replacing the motherboard and installing or removing a modem, ensure that the JMOD connector is configured properly. To see how the JMOD connector works, use keyword "JMOD" to bring up the document "How does the JMOD Connector work?".
Pin one on all jumpers and connectors will always be in the direction of the compass unless otherwise marked on the diagram.
There are three revisions of the PB 301 motherboard. Revision C was the only 301 used in multimedia systems.
