Here, in one place, are all the manuals we have for Digital Research software products. These manuals have been produced by scanning, and ocr'ing, the originals. Where possible, the look and feel of the original has been preserved as much as possible. The manuals presented here have been through an extensive clean-up process. OCR is not an exact art, at least not in the affordable software available for the PC, so a separate cleanup process is necessary to produce a pretty manual.
At the bottom of this page you will see a link to some manuals that have been scanned, and ocr'd, but not cleaned up. You can also participate in getting these manuals cleaned up.
NOTE : There is now a site to distribute the DTP sources for some of the manuals on this
site. Here is the link to it :
They are mostly in Lotus AmiPro and Microsoft Word format.
I'm in the process of converting them all to PDF format. The results will be posted here.
Still, there are a couple of manuals on this site available in Postscript format only. If you've got the possibility (and time...) to convert them to PDF, please let me know. Searchable (i.e. plain text) PDFs are preferred because of file size and online readability.
One more request: Though the manuals have been cleaned up, sometimes a small number of OCR
'misunderstandings' will be left. If you find them, please correct them (if possible) and send me
the corrected version.
You can contact me at email@example.com. Please don't send me any files by e-mail if I didn't asked you to do so.

Circuit Modeller for CP/M: 4.5M, by Harcourt Systems.
This is a user program to get manuals prepared for distribution. Tim and others scanned and partly OCR'ed them, and posted the results here.
If you would be willing to help, please check out what he had scanned, download it, and go to it. If you do, PLEASE co-ordinate with me so we don't have several people working on the same manual.
If you are desperate for a manual, you can take one from this page and try to use it. Just understand that it won't be pretty.
Most of the problems introduced by the OCR process are pretty straightforward. For those that aren't, there are several ways to address them. If you have another copy of the manual you are working on, you can refer to it to fill in the blanks in problem areas.
I'll try to carry on with Tim's work as good as possible. So if you got any
manuals done, please send them in, so that I can publish them in this place.
Gaby, firstname.lastname@example.org (please contact me before sending any files by e-mail).
