4 Level Brightness Control Function
The module includes the Vacuum Fluorescent Display
glass, driver and micro-controller ICs with refresh RAM,
character generator and interface logic.
The high speed 8 bit parallel interface is 5V CMOS
compatible suitable for connection to a host CPU bus
which can be set to M68 or i80 series interface by a solder
link on the module. Brightness control and power down
functions are provided. A full data sheet is available.

JUMPER LINKS
# Interface M68/i80
When jumper link MPU is
soldered, these inputs
change to i80 series CPU
control lines.
Pin 5= /WR Pin 6 = /RD
Pin 3 (Fnc) Input
This is normally open circuit.
If pads on R19 are linked,
Pin 3 = /Reset.
