In the t1 chip, the gm0,1,2 bits of the sam do other stuff than on the
original 6847.... According to the "new" SAM DOC...

The t1 has the ability to change the border colour from black in text mode
to either orange or green, i have experimented with it on a real coco2b, and
it works...

Hey Luis...

The xc80652p and the mc6847 t1 are one in the same beast...

Seems like the xc part number was a"pre-release" version... I have the same
chip in my coco2B....

And the 74ls785 sam.....

And the different pia 67331p......

The pinout plus "some" more info can be had on the t1 chip from "full turn
of the screw"... You can download it at my site:
