[Coco] Wolfenstein 3-D on a 4.77mhz 8088? So, 6809 port, anyone?

No, I'm talking to use 160 pixels (for 320x200 coco3, 16 color) mode. You
use a byte for each 2 pixels.

There is one thing about the PMODE4 artifact colors. Modern OSes (windows,
linux, etc) use a similar technique to create smooth fonts like Clear Type.
Take a printscreen, paste it into pbrush of any other graphic tool and
magnify it. Look the red and blue subpixels around the text. Does it
creates some nostalgia on you ?
