"...  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).'
