Desktop TN3270 Software

Printer-friendly version

For access to UCSB and UCOP mainframe services we recommend using the MochaSoft TN3270 client. UCSB provides a site licensed version for the Windows and Macintosh Desktop OS platforms which allows the emulator to be used without cost by University of California employees. 

The link below is to the MochaSoft TN3270 client download page. Please select, download and install the correct TN3270 client for your desktop OS. The information you need to connect to either UCSB or UCOP mainframe services is in the table below. You may wish to refer to our legacy client setup guides for tips on tuning session parameters. Once you have confirmed the client works, please contact your departmental IT Support who likely already have the license key. If they do not, please have them contact the Enterprise Technology Service Center as indicated below.
