I have this NEOS MA-20(R) which I bought thinking it was a complete set (and as such paid to much). It seems to work (if I insert it in an MSX it takes over control from the BIOS but fails because the MA-20(V) video board is not there). If you have the MA-20(V) but are missing this one I will send it to you for free 
If you are interested please send me an e-mail. The address is on my profile page.
