There were at least two versions of iMAX as of 1982, Version 1 and Version 2. Version 1 was undergoing internal Intel testing as of 1981 and was scheduled to be released in 1982. Version 2 was modular and the programmer could choose what parts of the iMAX operating system to load; there were two standard configurations of iMAX version 2 named "Full" and "Minimal", with the minimal configuration being similar to Version 1 of iMAX. As of 1982, a Version 3 of iMAX was planned for release, which was to add support for virtual memory.
