Using a futaba M202LD05AA from scrapped cash registers.

The datasheet is unavailable for this display, so dont even try...

I used old fashoned logic to figure out how to drive this display. it is an entirely controller-less display, its nothing more than a DC-DC converter that uses 5 and 12volts, along with a strobe, data, and clock line. (148 bit shift register + 16 ID bits).

This is the result. The creation will be in another video.
