Character generation

FTFROM supports eight character tables, each of (nominally) 128 characters. Four tables are in on-chip ROM and

contain fixed characters and four are stored in an external RAM. The fixed character tables (Tables 0 to 3), shown in Figs

15 and 16, are applicable to 10-lines-per-row applications. For 9 lines per row applications, the characters will be as

shown but with the last line removed from alpha characters and line 5 (labelling 0 to 9) removed from mosaic and line

drawing characters.
