I am with the Alaska Chapter of the 99s and we have
two of the ATC-510
 simulators (desktop model).  We do not have any manuals and one of them is
 giving us trouble.  I am looking for two bits of information.  1) How can I
 get copies of the training and service manuals and 2) where can I have them
 repaired?  Any help you can give me would be greatly appreciated.  Thanks,
