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

[davidlinsley at gmail.com]

I have two of those Premier Microsystems boards (a production and prototype), but without the VDG chips - I was given them around ‘92-93. I could dump the ROM (provided my EPROM reader at work still works) and scan the instruction sheets if interested.


Cheers,

David.

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.
