Re: A89: Should I make a "shell" for AMS 2.03?




My question:  Why exactly CAN'T they do greyscale?  What reason is there
for it not being able to?  I'm really an 86 person, but on the 86 you do
it by switching the memory area that is mapped to the screen really fast
through a port.  Isn't there a videomap port on the 89?  And a free
block of mem in which to switch the screen?
