It allows to connect either LCD submodules from various manufacturers or Fluorescent displays from NEC. Communication with the terminal can be established via RS-232 (standard) or RS-422, RS-485 or current-loop (optional).
The MPL4080-DEV, MPL4080B-DEV, the MPL4082-DEV and the MPL4083-DEV packages contain all the software needed to install and run the disk based OS-9/68k version 3.0 on a MPL CPU based system. Also included is everything needed for building ROM based MPL systems.
