"...  Apparently there is no such simple capability [inverting the screen] for the DLion.   That may explain why a call to ***  FLASHWINDOW *** doesn''t seem to do anything on a DLion..."'
But there is, THERE IS!'
With ABC loaded, do':'
(replace DLDISPCONTROL of \IOPAGE with 2048)'
to make the screen inverse video, and'
(replace DLDISPCONTROL of \IOPAGE with 32768)'
to cause the display to be filled with the border pattern, and prevent microcode access to the display (I guess that''s what DISPLAYDOWN does on the Dolphin/Dorado - am I correct?)'
Resetting those bits to zero will return the display to normal.'
I suggest that this be added to (VIDEOCOLOR) at least. '

I have edited VIDEOCOLOR appropriately.'
The other feature, disabling the display, should be used to make startup cleaner, but this requires a little coordination with the boot code (the boot ucode should set the disable bit before turning on the display ucode; Lisp then turns the bit off when it gets the display into place).'
