In the most recent issue of Analog magazine, there is a program
which uses scan-line driven interrupts to produce a display with
256 or 512 colours on the screen at once. The author claims to have
found the correct colour shadow registers and line-driven interrupt
information by trial and error. Does anyone know of documentation
on how the st hardware displays the screen? In particular
is it possible to do hardware driven scrolling by modifying
the hardware physical screen base at the end of each
scan line drawn?
