[NTLK] Does anybody have a Newton connection kit working with tiger

[Rufus Kohn]

So until I get a new cable they works on high Sierra I thought I get my Newton connected with an older Mac. First I went way back to a PowerBook 1600 on per OS X. Such a shame it died in my hands. But I still have a G4 with OS X tiger running. I got the keys pan working fine. Only I cannot seem to find a connection kit that works with it. 
 All the links that I found on internet seem to be dead ends. Any help is greatly appreciated.
