This collection is an attempt to gather all of the documentation needed to start programming the CoCo in any given language. All of these items can be found elsewhere, but it can be difficult to sort through the many possible locations and multiple versions to find what you need. In addition to (hopefully) finding the most current versions, I've optimized the PDFs for size and readability and performed Clearscan OCR on most. Using Google Docs, these references can be quickly viewed and searched online. In addition to the references found here, be sure to check out the NitrOS9 Documentation Wiki. |
