Your Mitel SX-200 Superswitch is a very old analog system and only supports the 9110-107-000 console. They stopped manufacturing it in the late 80's.
The Superconsole 1000 works on the digital platform so you would need to replace the main unit as well to make it work at your location.
You got your money's worth from that old Mitel!
