Finally, after a few weeks of waiting, I received this morning my two ANNAX ZM16C30 flip-dot displays. I'm extremely pleased with the packaging. Several layers of styrofoam, bubble-wrap, and foam sheets kept the precious boards and flippy dots secure during this journey across the globe from Australia to Spain.

Came with a personal note on a postcard :

And a small bag of several replacement dots. Some don't seem to be usable directly as some are missing their magnet. But nonetheless very appreciated and could be very useful to make some repairs at later stage.

Double wrap in bubbles and foam :

High quality manufactured board and clean dot matrix. Pretty happy with the product so far.

Some close up shots.

Now will start the reverse engineering. The board comes with two 40pins connectors, and a few other chips on it as seen above. I'll try next to find out what they are for, and which pin of the connectors go to which columns and rows. Stay tuned !
