Re: A86: 3-color icons?

<< That's right. The idea is to have two separate LCD buffers and switch
between them rapidly. If a pixel is on in both buffers, it will appear
black, but if only one is on, it will appear grey.
Actually, we could have 4 colors by weighting the times that each buffer
is displayed. One buffer would show 1/3 of the time, and one 2/3. That
would make transparent icons more complicated, but it would probably be
worth it for the additional color.
I suppose we could allow for 3 buffers, but that would use a good chunk of
memory and complicate (slow down) graphics. Besides, more than 4 colors
might not be easily distinguishable from each other.

could'nt the 86 support true greyscale (without turning pixels on and off
real rapidly)? Before the 86 came out l was messing with messed up programs
on the 83 (just typing in code like:
:71
:End
:0000
:End
and then running it as an assembly program. this particluar one, after doing
a few crazy things, would always at the end display the graph screen with
random pixels displayed and the calc would be locked up. lt would be frozen
up, but l could pick out about six dirrerent shades of grey. it would seem
to me then like this would be possible on the 86 but we would utilize it to
do something useful.
