Found a japanese version of the siig minitouch...cooool
This seems to be an ortek version, mck or mkb, but not sure exactly what the title is.
It's especially interesting that the backspace key was moved farther over to the right into the page key line to allow for the yen key to be in the number series, and the return key was diminished to a single line as well to allow for another key I'm not sure exactly what it is, after the p. I guess it's an @ key.
If this was the original format of this keyboard, and the english version was produced second to it, it might explain some of the arrangement of the siig minitouch, and why there's a blank key in the upper right.
I think this definitely puts a nail in the coffin of siig as far as being the producer of this keyboard. It's clear as with the plus version of the minitouch, they're just a repackager of a Japanese or far east produced board.
