[Note 1]
The upper left corner of the page is the character pattern 0-0, and from there to the right ~0-1, ~0-2, ~0-3,....
[Note 2]
The numbers on the page are the VRAM addresses (hexadecimal) of each character pattern name data, based on the VRAM address of the pattern name data of character patterns 0-0.
