Cool =) So, Amaze-A-Tron is MP3405, Merlin is MP3404. That makes me a bit more curious what the unknown MP3403 dump by kevtris could be. I should have a look at that later. I won't be at my dev pc for a few days.
Panasonic MN1400ML, may be an unlicensed clone? It was(still is?) common to copy designs and sell them yourself.
