Activating CG1 mode

I was wondering if the CG1 mode (64x64 4 color graphics mode) can be set on the Dragon.
I did try with a small assembly program but probably did something wrong.

Hello Robert
according to the book 'Anatomy of the Dragon' to set the graphic mode 64x64 4 colours you just have to do this
POKE&HFFC1,0:POKE&HFFC2,0:POKE&HFFC4,0 in order to set the SAM
And then POKE&HFF22,&H80 to set the PIA
cheers!

That worked beautifully!
I must have made some silly error when I tried before...
Thank you very much, Pere!
