Done before subscribing to this list, but thanks for suggesting that it 
was the right thing for me to have done.  I even went to the trouble of 
setting up the VGA adapter to 640x480, though OF is supposed to be smart 
(and tyrannical)  enough to override adaptors being set any other way.

As near as I can tell, setting nvramrc is only possible with `Boot 
Variables', not with `System Disk'.  Is it just me that thinks that 
having OF reset every time you boot into macOS counts as braindamaged 
design?

I thinkg I'm going to just hunt down another mac before continuing.
