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.
