ADL recently published a new website, but unfortunately didn’t include any 404 redirects so that old links will go to the proper new page. It can be kind of hard to find some of the things you might be looking for. Most notably, it seems as if there is no direct link to download the specifications, conformance test suite (CTS) and sample run-time environment (SRTE) for old versions of the standards like SCORM 1.2 and the prior editions of SCORM 2004. If you dig around a bit though, they are still there. You have to poke around in the breadcrumb that appears at the top of the page when you get to other downloads. Here are some direct links for your convenience:
Download SCORM 1.0 – Specification Only.
Download SCORM 1.1 – Specifications (look for the zip file under the mislabeled “Documentation Suite (SCORM 1.2) ” folder), and Sample Run-time Environment (be careful, there are other files from other SCORM versions that are mixed up in this folder).
Download SCORM 1.2 – Specifications, Conformance Test Suite and Sample Run-time Environment (all clearly marked).
Download SCORM 2004 2nd Edition – Conformance Test Suite and Sample Run-time Environment (all clearly marked), Specifications seem to be available in French only. I imagine they will fix that soon, but in the meantime here is the English version of the SCORM 2004 2nd Edition Specifications.
Download SCORM 2004 3rd Edition – Specifications, Conformance Test Suite and Sample Run-time Environment (all clearly marked).
