DISPLAY AND MODES
The display features three sections: numeric, dot matrix and fixed symbols. The numeric
section features a minus sign and 12 digits for the mantissa, as well as a minus sign and
3 digits for the exponent. The dot matrix is 6 dots high and 43 dots wide, allowing for
some 7 to 12 characters, depending on their widths. The fixed symbols (except the big
annunciators, and are for indicating modes.
The dot matrix section above is used for
1. indicating some more modes than the annunciators allow,
2. passing additional information to the user.

ferent formats, for status, or messages.

their priorities as follows:
