Subject: Re[2]: Grayscale Display/ Picture Viewer/ HDD Upgrade
From: Eric Linenberg (

In the end of the game SOKOBAN, if you pass the 101st level (or just
keep on hitting F3) then it flashes the entire screen. I think it is
EASILY quick enough for grayscale. You could have a 3 color grayscale
with just two different bitmaps.
