[Coco] So does your coco3 do 256 color mode ? Mine does...

[Luis Antoniosi (CoCoDemus)]

Actually right now the driver is a little faster as I optimized it a
bit. But the scrolling up will always be faster on CRT9128 because
there it's done with hardware registers. On 9958 I have to copy
VRAM-VRAM.

Also, to v9958 requires more writes to update each text position and the cursor.

But it does support colors. I have now a os-9 tool to change the
background and foreground screens.
