[Misc] Request: RP3100 Mac OS 9 Drivers

[unwork_inc]

I've recovered an old iBook G3 running OS 9 which I'd like to use a controller for my RP3100, but I can't find the Mac OS 9 drivers for this model.
They are not available from the Riso Download Center, and I can't find them anywhere else either.
May someone share their drivers with me if they have them? Any tips on how to get this controller running will be appreciated.

Thank you

Following up on my own post: I've found an original Riso CD containing drivers for Mac OS 9. I'm now struggling with connecting my iBook G3 to the serial port on the Riso through a Keyspan USB to serial adaptor. I'm inching towards success but not certain of anything yet, so any suggestions are still welcome.
