OS-9 for x86, PPC, and ARM users will need version 2.1 and an update for the PCF module to be compliant. Other products are compliant in current release.
Upgrades are available for earlier versions.
Microware also realizes that many applications had been built and marketed using OS-9 for 68K version 2.4. Therefore, we have also provided a solution for this formally retired and unsupported version. If you are using an OS-9 for 68K version prior to 2.4 you will need to either need to upgrade to version 2.4 and install the Year 2000 Solution for version 2.4, or upgrade to version 3.0.3. All of Microware's current development tools are Year 2000 compliant. These tools include Hawk v1.0 or later.
