Introduction

After a bit of looking at the signals with the scope and some fiddeling and disconnecting of the wires while using the display with the printer the pinout of the panels could be determined. The pinout of the MP620/MP630 is tested, the one of the MP600 is an "educated guess" and untested.

Panel MP600

The pinout is unclear. J102 should be similar to the J201 of the MP620 panel, but seems to have an extra pin for backlight (?) (5 volt) and something else (1,5 volt). There may also be some additional data lines or interrupts. J103 should be similar to the J202 of the MP620 panel.
