Puma 8HC with Fanuc 16-T Control, backup PMC

I'm working on doing some preventitive maintenance on our 8HC Lathe which has developed an intermittent boot-up glitch. I suspect power supply ripple and want to have a good poke around.

Before I turn it into scrap iron, I want to back up all the parameters to file.
I have found instructions for backing up the NC parameters for a Fanuc 16i control, and it worked for the 16-T
HOWEVER
When it comes to backing up the PMC parameters, this machine does not have a card slot, as is outlined in the procedure I have.
As I understand it, this is stored in ROMs and is non-volatile?

Question, Is there anything else I can do to back up the PMC parameters?
