CMI Legacy

Is there anyone who still uses CMI to connect to the legacy system , my c applications do uses the binaries and libraries for using the CMI functionality but i do not have access to the original source code , and since this is a very old stuff , i just could not get any source to get to knwo the source , If anyone still have it or knows about it , I would like to the how the implementation of CMI_CONNECT is done .

Will be great to receive a reply from anyone of you
