You can plug a second BOB into port 2, and that gives you access to I/O pins 1-25 - but this time they are labelled Port 2/Pin 1, for example. Similarly, you can plug BOBs into ports 3-5 for additional I/O. Port 1/pin 1, Port 2 pin 1, Port 3/pin 1, etc, are all different connections and that is how you get access to the enormous number of I/O pins.
This was true for me Neale so thanks for making it clear.
