Does anyone know an easy way to turn on and off the whole
video display on the MAC II (we have the MAC II color video
monitor, with color upgrade, if that's relevant)?
We want to be able to draw a screen full of images (which will
take us several hundred msec), and display this screen full
instantaneously (i.e., within a single refresh), and to be
able to turn the whole thing off equally quickly.
By the way, we are using lightspeed pascal for this application. 

THANKS!
