I'm trying to figure out the video part, there is a demo screen that is showing pretty high res in color, and this says 1024x600 and 256 colours- that is mighty impressive for a 6502, that is driving way more pixels that I ever saw in that era, so I was expecting there was some other chip being used as a screen buffer and graphics chip...
but it looks like the LCD has to be bit banged by the CPU data bus directly? I see the 8 bit data bus is going straight to the LCD thru a buffer IC.
I don't see where in the memory map there would even be enough space for a screen buffer that large to be located, so I take it you have to write you own graphics handling yourself and pick a spot in memory for it all?
