Thanks for the ping back.
Here is the link to the Linux Libre laptop.

There's information on how to install, a reverse engineered b43 driver on
gNewSense.
However, the git clone command:
git clone git://git.bues.ch/b43-tools.git
Comes back with "fatal: read error: Connection reset by peer".

The network adaptor is BroadCom 43... (output from lspci)
If I can get gNewSense working with wifi, then I should be able to get it
working in Trisquel.
As I'm currently, and forever working in the voluntary sector, I cannot
really afford to change hardware. I'm hoping that the Macbook (late 2007)
will just keep on working, without planned obsolescence.
Many thanks :-)
