; The internal font structure for Atari7800 needs a full set of 128
; characters. Each character is 16 x 8 bits.
; The font consists of 8 rows of data:
: row7
; row6
; row5
; row4
; row3
; row2
; row1
; row0
; Each row is 256 bytes long
; As we have 2 bits per pixel we need 2 bytes to represent
; one character. So we can fit 128 characters in this font
; When you later use the font you must address the characters as
; 0, 2, 4, 6, ... 254
; Odd indices cannot be used.
