Any version v22 or higher has 3/1-63.

3/1-63 was the last version ever released for the MkIII.

The nav OS disc is used for many different types of nav computers. So while the OS disc version keeps increasing as versions for MkIV and NAVI01, NAVI02 are updated, the version for MkIII stopped at 3/1-63


So any OS disc v22 or later is OK
