Software
Saltzer has been a designer or the inspiration for a number of important pieces of systems software, which are either still in use or have descendants still being used today.
- RUNOFF, a very early text-formatting program which was the basis for Roff and Nroff.
- PC/IP, the first TCP/IP stack for the IBM PC, which became the basis for a company called FTP Software.
- Kerberos, an authentication protocol, part of Project Athena, still used today.
Additionally, while technical director of Project Athena, he was supportive of the development of the X Window System, an open windowing system, still used and developed to this day on Linux and UNIX.
