Texas Instruments System 1500

This is a TI S1520 system with a 68030 processor. It ran the TI Unix operating system that was derived from AT&T System V UNIX Release 3. This system uses the NUBUS for I/O, the same bus structure used in some Apple Macintosh systems.

The entire TI server division was sold to HP in 1992.

The RICM has two of these systems that were donated by RCS/RI.
