Manual for the Advance Instrument OS-2100 Oscilloscope

Hi all

I'm looking for a manual for the old Advance Instruments oscilloscope, model 2100. Does anyone know it there is one available for download somewhere?

regards

Lasse

I have some additional info on the OS-2100. It is also known as Gould/Advance OS-2100. It has two plugins; OS2002Y and OS2005X. If anyone have a manual on those, and the scope itself, it would be perfect. I would gladly pay for a copy.

Regards

Lasse
