The mouse M-31 was released in Japan by Elecom. The product name is "EGG Mouse".

The 200 written on the mouse refers to the "counts per inch".

Note: There is also another version of the mouse, which looks practically the same, with a 9-pin mini DIN connector, this one is not compatible with the MSX.
