You could do a similar trick (I think it's similar anyway) on the CoCo 1 and 2 in the Semigraphics modes. Each byte of video memory corresponded to 1 charaxcter cell width by 1,2,4, etc scan lines. You were _supposed_ to put bytes with the high bit set there, in which case the lower bits determined the colour and on/of state of the 2 halves of the cell. You could actually put any character there, whereupon the appropriate dots example, have the uppper and lower halves of the character cell coming Pity the CoCo 3 didn't support the semigraphics modes. -tony
