The Wavy /MPC 10 is a classic MSX 1 computer with 32 KB RAM (some sources say 16 KB).
Its main particularity is to be delivered with a light-pen. There is of course a connector to use it, and more surprising a hole is placed at the top right part of the case to store the light-pen when not in use!
The MPC-100 seems to be the same computer with 64 KB.
