The Daewoo DLP-01 is a Light Pen Unit consisting of a cartridge with attached pen and a switch. The unit includes a 8kB ROM with a drawing program (Lightpen Graphics) and new MSX-BASIC instructions - see Expander BASIC.

It's actually the same product as the Sanyo MLP-01 and has been manufactured by Sanyo, as the PCB clearly indicates it. The HAL/Sanyo copyright has been replaced by a Daewoo copyright in the firmware and the Japanese texts have been translated in English.

The switch allows to enable or disable the launching of this firmware when the MSX is turned on. With the ROM switch OFF, the light pen can be used by other programs that specifically support it, although very few programs are known to support it.


  • A light pen requires a CRT display. It cannot be used with modern LCD displays. In addition this unit can only be used with MSX computers with NTSC composite video out.
  • This external interface can be used simultaneously with the internal lightpen interface of the MSX2 computers manufactured by Daewoo.
