HP71B AC Circuit Analysis ROM manual

[pamphonica]

Can anyone point me at a scanned copy of the manual for the HP71B "AC Circuit" ROM?
I recently got this ROM in a nice HP71B (my 7th, or 8th, maybe!) and would like to try it out but cannot find the manual. It apparently runs a program called CNAP (according to Sylvain's compendium).
Many thanks
Jeremy

Thank you Sylvain. I'll give it a try once I've got my head round the process for defining the branches!
all the best
