ATARI ST - monochrome (71hz display) demo from 1987

Rare demoscene production, ATARI ST monochrome mode demo by deft of TAS in 1987. This playback was digitally grabbed at 60fps so everything is a bit slower than on the original machine. Right side of scrolltext does not flicker on original monitor, instead it appears to be grey.
Very few demos were coded in assembly language and running at 71fps for the ATARI ST in monochrome mode.
