Kurzweil Mark 5 setup file

Does anyone know of a source where I could find a setup file to import into Cubase for my Kurzweil Mark 5 keyboard? I tried the Kurzweil site but they don’t list it in their downloads. I realize this is an old keyboard but the sound is great so I’d like to be able to use it for output. I am new to Cubase and MIDI in general so if I am missing something here please let me know.
