The Apple A/UX operating system is a full implementation of AT&T's UNIX System V, Release 2, Version 2 (with BSD 4.3 extensions) for the Apple Macintosh II family of CPUs and the Macintosh SE/30 personal computer. This industry-standard multi­tasking operating system pro­vides higher education, govern­ment, engineering, scientific, and OEM/VAR users with excellent support for software develop­ment; research; computer-aided design, engineering, and manu­facturing; technical publishing; office productivity; and database applications. Version 1.1.1 enhances the usefulness of A/UX by allowing more Macintosh applications to run in the A/UX environment, and by broadening the range of platforms it supports to include the Macintosh IIci and Macintosh SE/30. It also supports the op­tional X Window System add-on product and conforms to the POSIX Federal Information Processing Standard (FIPS).

  • Ability to run many 32-bit-compatible Macintosh applications
  • Support for color through the Macin­tosh Toolbox and X Window System
  • Runs HyperCard Version 1.2.2
  • Support for POSIX Draft 12 and FIPS
  • X Window System Version 11, Release 3 (optional add-on)
  • Serial Line/Internet Protocol (SL/IP) support
  • AppleTalk for A/UX Version 2.0 (included with A/UX Version 1.1.1)

Details

Macintosh Applications Execution

A/UX Version 1.1.1 allows many 32-bit-compatible Macintosh applications to run in the A/UX environment. Macintosh applications that adhere to the specifications for the Macintosh 32-bit environ­ment, as documented in the Inside Macintosh series, run in the A/UX environment without change. Most Macintosh Toolbox features-including color and printing-are supported. Sound and direct hardware access are not available.

POSIX Support

A/UX is compliant with both the Federal Information Processing Standard #151 (FIPS) and the POSIX Draft 12 standard. The federal govern­ment created FIPS for POSIX Draft 12. POSIX is the trade name of the IEEE Pl003 standard for the UNIX op­erating system.

Apple Tape Backup 40SC Support

A/UX supports the UNIX archival utilities, including tar and cpio, for the Apple Tape Backup 40SC, which uses preformatted DC2000 1/4-inch tape cartridges in QIC-100 format.

AppleCD SC Support

The AppleCD SC drive can be used as a read-only A/UX file system of up to 500 megabytes, giving information systems providers an inexpensive distri­bution medium.

Multiuser and Multitasking Support

A/UX supports multiple processes per user, enabling one interactive application to run many subtasks at once. Applications that don't use the screen, such as network communications and printing functions, can also run invisibly behind another application. With term or the optional X Window System add-on, multiple interactive programs may run simultaneously. A/UX also supports multiuser activity via two back-panel serial ports or via third-party add-in boards.

Communications

A/UX provides standard UNIX communications such as cu and uucp, as well as more advanced UNIX facilities such as Berkeley Networking Services, NFS, Yellow Pages, and Mail. Serial, Ethernet, and TCP/IP support are provided. AppleTalk for A/UX Version 2.0 supports AppleTalk printing over LocalTalk and EtherTalk networks.

Text Editing and Processing

Text editing and processing utilities include vi, ex, ed, ditroff, nroff, tbl, eqn, and pic. A/UX also includes Adobe Systems' Transcript utility for formatting output to the Apple LaserWriter printer.

Programming

A/UX offers an assembler, a C compiler, debuggers, the Source Code Control System (SCCS), and related tools to assist in developing new applications or porting existing software to A/UX. It also includes a set of UNIX libraries that allow C programs to access the functionality of the Macintosh Toolbox, so that A/UX applications can present the graphics-based user interface familiar to Macintosh users, in addition to the traditional UNIX appearance. Numerous other languages and tools are available from developers.

System Administration

A/UX simplifies configuration and recovery. It automatically configures the smallest kernel possible, and simplifies the manual addition of new drivers. In addition, A/UX keeps redundant copies of crucial files so that, in the event of a damaging system crash, it can automati­cally return the system to a networkable state.
