I'll poke around and see if I still have a manual for this somewhere... 
I worked at the HP division
where they were built... I also have a few 1640 boards floating around, 
but I don't know if they
still work...  As I recall it was a pretty straight-forward serial 
analyzer, mainly rs232, though I think with
the correct probes it could do current-loop, etc. The front panel has 
all the possiblilites on it...

Good luck!
