I just spent some time googling how to change the screen memory that the 80-column text display is pointing at and didn't find anything relevant. Can anyone recommend a good book or other documentation relating to the programming of 80-column text mode?
There's only two places it can point: page 1 (0/0400-07FF and 1/0400-07FF) and page 2 (0/0800-0BFF and 1/0800-0BFF). I'm not even sure if page 2 works with 80-column mode.
