About Manx

Manx is a catalog of manuals for old computers. Manx is an open source project hosted on CodePlex.

Many of these manuals can't be found by search engines because the manuals have been scanned but haven't been converted to text. Google can index deep into these scanned documents because they will OCR scanned images in PDFs and index the resulting text. However, manx contains additional metadata on the online documents as well as information about documents known to exist but not available online. Manx's search engine is currently limited to searching part numbers, titles and keywords of these manuals.

This catalog mostly covers manufacturers of minicomputers and mainframes, or associated devices such as terminals and printers. Tiziano's 1000 BiT is the best catalogue for microcomputers.

Manx currently knows about 21653 manuals, 9547 of which are online, at 59 websites.

The list below shows the websites included in Manx. As Manx is still being built, you will find that not all of the holdings of these websites have been catalogued. If you know of manuals on other sites, please create a work item for the Data component. Even if a site only contains one manual, it is worth including. This list is ordered by date of inclusion in Manx.

Some of these sites are marked as being Low Bandwidth. They are either on a home DSL line, or the owner has indicated that they should not be mirrored with tools. It isn't a comment on the usefulness of the site!
