[sci.electronics] Video Controller IC - TMS9929

	Hi Folks, Ive got a question to ask, that some of you designers
may be interested in helping me with.

	Ok. I am currently designing a video display for a system I have almost
finished. But the display is becomming a problem due to the lack of parts in my part of the world.
	To date I have drawn up Idea's around the TMS9927. It is a 40 pin
ic that controls the complete RGB process for a video display. But it cannot
handle 80 column text, nor a reasonable high resolution, let alone speed.
It does have sprites, collision detection etc.

	Does anyone recommend an IC or an IC Chip set to handle the following.

	
*high resolution  (aaprox 400x400 or greater)
*clean text, simple character generator implementation.
*reasonable speed (5MHz)
*easy programming and programming free timing (eg. HSYNC)
*RGB Output
*Common and available
*good doccumentation for interfacing
*not to require anymore than 8 Address and 8 Data lines
*the ability to have its own memory array with its own cas and ras
*if so then 8 bit memory
*Be PAL compatible (Or depending on the clock frequency)


	Well thats all I can think of. if you have any idea's i would please
to know.  Thanks in advance
