Least there's been no changes from "final draft" to publication there then
:-)

Aha.  Hadn't come across one of those.

That's a good idea.  Amongst Rockwell-oids only Supra seem to have taken
further steps to store such data.  For Zooms we're still able tho to
either interrogate s210 or use %q1 in command mode
