Hi Aindrea,
the oldest SDP-RIP which works with your 1630 IIIR is v7.x. All later 32bit SDP-RIP v8, v9 & v10 will run too. All these SDP-RIPs are USB dongle protected. So, you will always need the compatible USB dongle for your SDP-RIP to start your RIP.
I have some, but not every SDP-RIP installers on my server. Let me know your USB dongle and perhaps I have the right installer for you.
