Most items are in PDF form. Things that I have scanned are often
offered in two forms: a PDF, and a ZIP file containing the collateral
files used to assemble the PDF. Some PDFs are scanned page images,
possibly with OCRed text underneath the images. Other manuals were
"born digital", and are native PDF. Some items are ASCII text.
There may even be some IBM or DEC "book reader" manuals here.
- Documentation by and about Digital Equipment Corporation products.
Most of the items in this section are things I've scanned.
Other repositories such as Bitsavers and ManX provide far
more complete collections, though the manuals here may not be
- Documentation by ETHZurich.
- Communications equipment documentation by Hayes Microcomputer
- Documentation by and about International Business Machines
products. Most of the items in this section are things I've
scanned. There are a few things here that came from e.g. the IBM
Boulder documentation site, because they're easier for me to find
this way. Additional IBM materials may be found at Bitsavers
- Documentation by and about Michigan State University systems.
All of the items in this section were scanned by me.
- Documentation by the University of Michigan and others for
the Michigan Terminal System. Some of these items were scanned
by me, others were produced using the MTS documentation system
by the group working to preserve MTS software. There is much
more material at the Michigan Terminal System Archive.
- Documentation by and about Prime Computer products. This material
was scanned by several people, including Jim Wilcoxson, Jim Cosper,
Al Kossow, myself, and others. This section includes all of the
available Prime documentation of which I'm aware, including all
of the material that is still to be found (differently arranged)
- Documentation by and about Teletype Corporation products.
