ROM addressing
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.
