LCD DOT-MATRIX INTERFACE

17.
To connect a LCD dot-matrix display, the MOPS/386A offers an interface with 16 signals.
This interface can support character LCDs for up to 40 columns and four rows, which are
equipped with a Hitachi HD44780 controller or a compatible one. A BIOS extension of the
MOPS/386A controls the outputs to the display via software interrupt INT10hex. You can
only use this feature with DOS.
Note: The LCD dot-matrix interface uses the signals of the onboard parallel port. In most
cases, this will cause problems if you use the parallel port with a device parallel to the
LCD.

Connector
