I discovered something interesting about the Chinese 32-bit Subor Wii clones that I thought would be worth sharing here.
If you're familiar with the Wii clones Lexibook released during 2015-2017, you may have seen a version of their consoles that somewhat resembles the Wii in design and looks like
this. It was released as the JG7420 and saw distribution in both Europe and the United States (I'll probably make a post on the latter specifically soon). What most people don't know is that Subor did release this version themselves in China under a few different names. I'll be focusing on the release named the SB-A10 (or "SMARTstation" if you prefer) in this post.
As it turns out, the Subor SB-A10 Wii clone actually has a notable difference from the Western Lexibook releases of the hardware: the addition of a 9-pin connector. It's located on the back of the console and is labelled "PAD". What this port is used for isn't exactly known as even on the Chinese speaking side of the internet, it doesn't appear that the 32-bit Subor consoles have much documentation to my knowledge. If I had to take a guess though, it was probably intended to be used for a peripheral of some kind (perhaps a wired controller going by the name the port was given?). On a particular Xianyu listing I found selling an SB-A10, though, the console also had what look like two PS/2 ports on the back in addition to the other connections, which I've attached pictures of here. I'm not sure what the purpose of those ports are or how common this revision of the SB-A10 is. Based on my understanding of how the Chinese versions of this hardware work though it's likely they're just normal keyboard and mice ports. So many mysteries, yet so little time.
