Raspberry Pi Model B, Rev. 1

The very first released version of the Raspberry Pi model B (rev. 1) has some minor pinout differences from the rev. 2 that followed. This is the only version of the Raspberry Pi that is not compatible with later pinouts. The incompatible pins that changed are highlighted in bold in Figure C-3.
