     I am looking for some card that will allow me to do real high
resolution multi-color work on an Apple //e.  You see, I am doing
experiments that involve scanning a surface and displaying a signal
amplitude at each point as a color.  I am willing to buy either a
really good composite or RGB monitor, but I am having trouble
finding cards for the //e that allow you to do graphics on a par with
IBM PC EGA graphics.  The requirements are as follows:

	1.  At least 350x350 dots (400x400 preferrable).
	2.  Able to display each dot as one of at least
	    16 different colors or shades.
	3.  It must be relatively easy to program from
	    Applesoft; i.e. it should come with software
	    that contains machine language subroutines
	    do plot dots with a simple call with simple
	    x,y,color parameters.

The price isn't really that important, unless the card and monitor
would end up costing as much as trading up to an IBM PC with EGA and
similar A/D hardware as is in the Apple now.  The data is stored
in a random access file of x records of y fields each on a Profile,
because the Apple's pitiful 128k can't come close to storing enough
data for a 400x400 matrix of 8 bits per point, just in case that's
relevant.

Thanks in advance,
