Gosh, please don't do that! What a terrible piece of advice. A large portion of the HP manuals are unavailable, and HP doesn't have them either. I have been looking for the operating and service manual for the HP 12050A (HPIB fiber optics extension) in vain. Couldn't find the one for the HP 7225B (gantry XY Pen Plotter) online, but found a hard copy version on ebay. Couldn't find any doc on the personality interface on it. On the computing side, many of the interface cards for my HP 1000 are undocumented or missing critical documents. Often a user manual is available, but not the service one. Sometimes you find the A, but not the B and they are significantly different. Etc, etc... And I am not talking obscure instruments at all.
