It is a 20x2 chars display, PCB is 176x51.5mm, active area is 100x15mm,
5x7 matrix with seperate cursor, charsize is 3x5mm (without cursor).

It has a 3-pin connector for the power supply on the left and a 26-pin
data ribbon connector like on a internal lpt connector (with plastic
frame) on the right side. There are no jumpers or aother connector on
the module.

That are all the facts i have. If usefull i could make a photo and send
it to you, but not to the whole list. Don't want to spam the net ... :)

The part number is correct, i have it written down as i can read it from
the PCB.

This will be no problem. A MAX232 should help, if i have read right in
the net ...
