ULTRIX was DEC's official UNIX for VAX, PDP-11 and DECStation/DECsystem (RISC) equipment.
Contents
PDP-11
ULTRIX-11 was available for the PDP-11 and can be obtained up to version 3.1 from the TUHS archive (below). It will run under SIMH (and other PDP-11 emulators).
These are the known ULTRIX-11 versions and predecessors:
- 1981: Unix/v7m V2.1
- 1982/83: V7M-11 V1.0 (= ULTRIX-11 V1.0)
- 1984: ULTRIX-11 V2.0
- 1986: ULTRIX-11 V3.0
- 1987: ULTRIX-11 V3.1 (last version)
VAX
ULTRIX-32 (from version 4.0 onwards called: ULTRIX/VAX) for the VAX was derived from 4.2 BSD with some influences from SYSV and included support for specific DEC technologies. The latest version is 4.5 from 1995. Earlier versions of ULTRIX-32 are available from TUHS. It will run under the VAX simulator in SIMH.
Timeline of the main VAX versions:
- 1984: V1.0
- 1986: V2.0
- 1988: V3.0
- 1990: V4.0
DEC MIPS-based Computers
ULTRIX/RISC for DECstation and DECsystem computers is not available from TUHS. The latest version is 4.5 from 1995. This version will also run, (Including CDE + X11!) under GXemul.
Y2K compatibility
It's been confirmed that 4.0 is NOT Y2K compatible... Not many UNIX from the 1990's or prior are so it's really no surprise...
Running ULTRIX
SIMH will run Ultrix. Many simulators -if not all- of supported VAX computers are known to work.
Installation instructions for SIMH can be found at:
- Installing ULTRIX-11 V1.0 on SIMH
- Installing Ultrix V1.1 on SIMH
- Advanced Installation of Ultrix V2.0 on SIMH
- Setting Up RIS on ULTRIX V2.0
- Installing and Configuring an ULTRIX V3.0 DMS Server on a SIMH MicroVAX 3900
- Installing Ultrix 4.0 on SIMH
- Installing Ultrix 4.5 on SIMH
