some text into the graphic area and actually change the graphic, or plot 
some dots into your text to get some weird changes in the displayed 
text. Bits 0-3 stood for the bottom part and bits 4-7 for the top part.
As the text was strictly black and white, upper case only, there was no 
foreground/background play. Text could be writen in normal (white on 
black), inverse and flash, or blink mode. Inverse was triggered by 
turning bit 7 on, and flash, IIRC, with bit 7 off and bit 6 on, but not 
for punctuation and special characters.

I still have my Apple ][+ 48K, with all it's documentation.
