This is a Macintosh version of ISCA Client 1.5. It was done in one day, so it's very faithful to the original UNIX version (that is, it lacks a Macintosh interface). Please make sure that you log out (using the "L" key) before choosing Quit from the File menu.
I'm not on ISCA very much (if at all) these days, so you should ask questions in the Client forum on the BBS.
