Don't we all. Unfortunately, the current chipset can't deliver that
many colors at the resolution you specify. 16 colors at 640x400 max,
unless you want to start playing with copper lists, as others on the
net have mentioned. But I don't think that is a good solution for a
highly dynamic environmnet such as the Workbench, where windows and
images are constantly being moved about.
Anyway, the current Workbench is limited to 4 colors (two bitplanes)
because any more bit planes would start stealing bus time from the CPU
for the display memory access, resulting in a loss of performance.
2) Ideally, this would also be the standard resolution for actual
drawing programs as well. This would prevent that annoying switching effect
one notices on ibm at's and their clones.
Well, the Amiga offers multiple display resolutions, but it doesn't
suffer from that "annoying switching effect" you describe. It comes
from having non brain-dead video hardware, and software which was
designed to allow different video modes to coexist on the same display.
3) Please note that I am willing to spend up to $1200 (cdn) for a well
defined and integrated set of display equipment.
And I'm sure some of the people in this newsgroup would be willing to
spend more. But sadly, we have to wait.

Hi once again. There were a few deficiencies in my previous post: 1) I want 640x400 x 256 colours (or 800x600 x 256) to be used in standard windowing operating system (intuition I believe) mode. i.e. this is before any specific graphics application such as drawing S/W is considered. This would allow for the various system icons and windows to be much better defined on the screen and take up less room. 2) Ideally, this would also be the standard resolution for actual drawing programs as well. This would prevent that annoying switching effect one notices on ibm at's and their clones. This one res. fits all mode is what exists on the sun: 1152x900 for both text windows and graphics. 3) Please note that I am willing to spend up to $1200 (cdn) for a well defined and integrated set of display equipment. ------------------------------------------------------------------------------ Tim Lapin |_____ INTERNET: timl@maxwell.concordia.ca | Printed Opinions?
