Disklavier

Guys and Gals,

I am new in the disklavier world. Since 1990, I always wants to have a 
disklavier. However, at the time, disklavier was too expensive. Last 
month, I happened to find a used disklavier but in very good 
condition. 

Could you please let me know if a new disklavier player that is 
connected to current model DU1 can be connected to an old MX100 II.

Any help is really appreciated.

RS
