About two old manuals

Regards:
I am looking for the complete manual of the old Graphtec WR8000 graphic recorder, (the WR7700 can be used). and also the Operator's Manual of the Saturn SD380 an FFT signal analyzer. On the internet I have only found a very brief information of the WR and partial information of the SD380. Someone could tell me where to find it.
Thanks in advance

The **broken link removed** was the first hit on Google searching for "Spectral Dynamics SD380 manual".

Greetings:
I return again on the subject that I raised long ago on the SD380.
I would like to ask an expert about the differences between the SD380 and the SD385.
It looks as if the SD385 is a portable version of the SD380.
Am I right, or is there a deeper difference?
Thanks in advance.
Joaquin.
