I'm just going to drop this off right here. To the left is the diagram for the stealth VIII. To the right is the diagram for the MultiMode 3 (with the second soldering point obscured by a textbox for some terrible reason). Notice anything, you know, similar? Is there a particularly good explanation for this? Are the chips programmed differently, or is it a case of jerks trying to make a quick buck off of people who don't do their research?
