[Coco] NitrOS9 question

Dave,

That is interesting.  Since in the headless options in the repo I don't see
the VTIO listed in the modules.  I know as I used the Toolshed's OS9
utility to ident one of the bootfile's and I didn't see VTIO in there
anywhere.

Though there is a disk image for becker_headless.
