Need help!!! Robot Fanuc S-420F 1993 year controller R-J

I urgently need help. We bought on auction Robot Fanuc S420F, with controller R-J and I asked them to send us all the documentation but the seller did not send us even one single page so we are in very difficult situation. I kindly ask anyone who can help to send me where can I found documentation for it.

One more question....
How to run the software?
See my photo..

Thank you in advance for answers.
