[comp.sys.atari.st] Horizontal Scrolling on the ST

SML108@PSUVM.BITNET (11/21/89)

Does anyone out there have any idea how the demo program Tayskuva from
Level 16 achieves its horizontal scrolling and overscan ?  It's a really
nifty trick, but all I can figure is that they're scrweing with shifter
registers during vertical and horizontal blank.... Any ideas ???
