Service Manuals, Internals & Misc.

These documents are reproduced here with the permission of Hewlett-Packard. These Acrobat (version 3.01 & 4) PDFs may be viewed on screen or printed. Because they are scanned at high resolution, printing is recommended. Acrobat readers for a large number of platforms may be freely downloaded from Adobe. Blank pages have been omitted from some of the manual scans to save space.

Note: Additional HP-IL information is on CD 3 in the options section.

Missing Pages

Some volunteers omitted blank pages from the scans and others kept them. While the scans have been browsed for readability and completeness, due to the size of this project, there may be missing or duplicated pages. Any missing pages will be posted at www.hpmuseum.org/cdupdates/ for downloading.

Acrobat Speed

If you find that the Acrobat plug-in for your browser is slow, you may prefer to run the stand-alone Acrobat reader. Download the appropriate reader (see above), go to the manuals directory on the CD and double-click the appropriate pdf file.
