Notes: 1. EPROM addresses A10 to A3 correspond to a character code.
2. EPROM addresses A2 to A0 specify a line position of the character pattern.
3. EPROM data O4 to O0 correspond to character pattern data.
4. A lit display position (black) corresponds to a 1.
5. Line 8 (cursor position) of the character pattern must be blanked with 0s.
6. EPROM data O5 to O7 are not used.
