Hi Steven and all

Yes, according to the Vine Master OS Overlay board info, Terminal and
MOS contain vital components that cannot be removed. View contains some
graphic extension commands. If you are not going to use them, View can
go.

I am presently looking into reproducing this board, I have the track
negative. If anyone is interested in getting hold of a 'made up' or kit
version of the Master OS overlay board, please let me know, it may spur
me on to move it up my list of 'jobs to do'.
