CDOS-68K is at revision level 1.2, while CDOS-286 was upgraded to rev level 1.3 (at which point it became FlexOS 286). The significance of this to you is that no enhancements or maintenance of the 68K version is planned in the near future (unless a "major" OEM contract should happen). So the 68K O/S is pretty much being sold only on an "as is" basis.
