... the first and proven software to run OS3 on UNIX
If you have COBOL, RPG and/or BAL ASSEMBLER software on UNISYS/OS3,
which is worth bringing into the 21st Century to run on a UNIX-Platform,
we have the experience and the tools to perform this task.

We developed TCS, which enables your application to run on UNIX.
TCS is also available for LINUX.
OS3 to UNIX - we've been doing it since 1988.
