Fortunately, there is no system ROM revision higher than 'O'.
The latest CX ROM revisions are "NFL" for the mainframe ROMs.

The revision of the internal CX Time and X-Function ROMs can be read in the same way using the 3FFA and 5FFA addresses, but it's much easier to get the revisions from the CAT 2 headers.
