PTIONS
A number of pre-defined character sets are available to cover regions throughout the world. These are listed in
Table 29.
The character set option Pan-European is shown Figure 31 on Page 69
.
The Closed Caption character table is shown in Table 30 on Page 80.
ROM A
DDESSING
Three ROMs are used to generate the correct pixel information. The first contains the National option look-up
table, the second contains the Basic Character look-up table and the third contains the Character Pixel
information.
Although these are individual ROMs, since they do not need to be accessed simultaneously they are all
combined into a single ROM unit.
