Atari Home Computer

This is the start of "season two" for T.M.R's monthly demo series and another raster bar laden spectacle. MD201701 was assembled from a couple of prototype routines for release with the now traditional New Years Disc. Music this year comes from Sack and is a cover of an old nine channel AdLib tracker tune that was doing the rounds in a couple of editors; it's also a couple of patterns short because he was somewhere in Alicante with limited internet access when T.M.R asked for music!

Trivia: The raster bar routine writes a hue value to the background colour but uses sixteen scanlines of bitmap data to generate the luminance, allowing it to pick any colour in the Atari 8-bit's palette; there's also six buffers being used for the colour data and some palette rotation going on to create an illusion of movement.
