JMRI has a Raildriver Throttle to control model railroads. It works but the RailDriver calibration app is missing from the JMRI files. If anyone has this file
which may be named ( RDCalibration.jar ) please let me know or upload it to the jmriusers group on yahoo. JMRI is an Open Source project so it is ok to post the missing file.
