there any examples other than 10.4.10? Was there a 10.x.10 for any

Or even an x.y.10 for any Classic version?
It's kind of strange that it didn't work for 10.4.10. I mean,
presumably the whole point of turning "10.5.2" into "1052 base 16"
instead of just using decimal 1052 is so you can go higher than 9 for
each component. But perhaps, given far back the feature goes, it
was always intended to be binary-coded decimal, and the goal was
simply efficiency: you can mask out the fields you want with fast
bitwise ops, no division required.
The limitation is that the "minor" and "release" values were always
stored as side-by-each BCD nibbles: <http://developer.apple.com/technotes/tn/tn1132.html
