Actually, the real reason that you want to load the look-up table
during retrace is to eliminate contention for the look-up table 
memory.  We have a Grinnell 27 and it doesn't load at that time
and so there is contention which shows up as snow on the image for
brief periods.  Very distracting if you are trying to do animation
and are thus changing the table continuously.
