1996 is the S1500's 10th Anniversary !!!
The S1500 series of Unix servers was introduced by Texas Instruments in
1986. From the beginning, the S1500 was concepted as a multiprocessor-
capable system. Several different S1500 systems were produced:
- S1520 - 6 NuBus slots with up to 4 (5?) CPU boards
- S1505 - single-CPU system in minitower style (CPU 68030@25 MHz)
- S1507 - single-CPU system in minitower style (CPU 68040@25 MHz)
- S1508 - dual-CPU system in minitower style (2 68040 CPUs @ 25 MHz)
- S1580 - rackmount 1500 system - I don't have any information on these ...
The 1500's operating system, TI Unix, was derived from AT&T System V Release
3. The final release is TI Unix 3.3.2. TI added several extensions to the
stock AT&T System V :
- Multiprocessor support - up to 4 CPU's are supported by TI Unix
- TI's bsh ("business shell") - an extension of csh
- various tools to support system administration (devadm etc.)
- the tx editor and the dfm file browser. tx was a look-alike to the editor
used on the 990 series DX10 operating system.
In 1992, TI sold the complete Unix system division to
Hewlett Packard (hp).
