 |  Re: Bit# 4 of TEd register $14
@Mad: try to set the FF14 to any legal text address (say $0C) and then perform GRAPHIC 2 or GRAPHIC 4. Test again $FF14 and you'll find $1C.
If you hit GRAPHIC 0 it will become $0C.
Even if I did not  I believe that the old masters did know this. It seems that to set Hires attributes address area to, say $7800, they had to write $6800 inside register $FF14 before to use the Hires.
Any further info is welcome
