That's going to be important information if you are going to be trying to write software to it.
What language are you writting in?
I'll take a look around and see what I can find on the TN, if it has similarities to the AP3 system and you are writting the code in COBOL I may be able to help out a little.
Not sure if they have a drive. There is an old AS/400. Had assumed the software would be FTP'ed onto the host, but maybe that isn't possible.
See PM. And thanks.
