Mobility Robot Integration Software

I am the owner of a B14 and a B21 robot manufactured by RWI in the 1990's. It is my understanding that iRobot purchased that company. I am
in the process of refurbishing these robots as they have been in storage. However, I am missing the original software installation discs for the robots. I need a copy of RWI's Mobility software drivers to control the robot's hardware. Does anyone know if a copy of the software is available or can be purchased? Or does anyone have it and can get in contact with me? We still have the original manuals and licenses, but not the discs. Thanks for your help.
