ATARI ST Mouse Kit is a shell that fits Wireless Mouse Components Kit 002.
There are 3 versions included. With Atari logo, no logo, and ZX logo ( LOL :) )
Buttons need connectors, grey on the photo, then just put them in. If it's too loose put a drop of superglue on those connectors.
The rest is the same as other mice for kit 002.
