Autodesk AutoCAD (1984) 25 Graphics Engineering Unix

AutoCAD, from Autodesk and first released in 1982, is a powerful Computer Aided Design tool. It was, and still is, often considered the standard for CAD tools. Primarily for the IBM PC platform, it was ported to x86 machines with higher video resolutions such as the Zenith Z-100 and NEC APC. Intermittently, versions for the Macintosh appeared. Later versions use a dongle copy protection.

IRIX (1998) 24 Unix

IRIX was a operating system created by SGI (Silicon Graphics Inc) that was based off of System V Unix. In addition, this OS had additional BSD elements. It's initial release was in 1988 and was designed to on MIPS processors. IRIX machines were typically used for visual effects in the entertainment industry and in the scientific community for several years after the fall of Amiga in the early 90s.

Lotus 1-2-3 (1983) 97 Spreadsheet Unix

Lotus 1-2-3 was an early spreadsheet application available for MS-DOS. It became extremely popular in the late 1980s, displacing the former leader VisiCalc. Lotus had difficulties adapting 1-2-3 to the Windows environment, and was overtaken by Microsoft Excel. Spreadsheet functionality was also included in Lotus Symphony. Later versions were included in Lotus SmartSuite.

Although Microsoft did not invent BASIC, their founding product was a BASIC interpreter for the Altair computer. The descendants below includes Microsoft's BASIC-80 (MBASIC), BASIC-86 (pre-GWBasic), BASIC for Mac, BASIC Compiler 86/88, Basic Compiler for Mac, and Professional Development System 7.x. IBM Personal Computer Basic Compiler, GW-BASIC, QuickBasic, and Visual Basic are listed separately.

Microsoft Word (1983) 176 Word Processor Unix

The Microsoft Word word processor was first introduced for MS-DOS in 1983. Its design made use of a mouse and WYSIWYG graphics. Its crude WYSIWYG/mouse support was a direct response to the Apple Lisa/Mac, and VisiCorp Visi On. Initially it competed against many popular word processors such as WordStar, Multimate, and WordPerfect. Word for DOS was never really successful.

NEWS-OS (1989) 0 Unix

NEWS-OS was a variant of BSD (later System version V UNIX) developed by Sony for use on their series of work stations called the Sony NEWS (Network Engineering WorkStation). This machine was a desktop replacement to VAXes in japan, created in 1987. NEWS-OS was designed specifically for use on computer networks, and had support for the TCP/IP protocol, something that wasn't commonly used back in the day but now required for today's machines. Versions 1-4 of NEWS-OS used 4.2BSD as its base. Versions 5 and 6 used UNIX System V 4.2.

PC/IX (1984) 9 Unix

Interactive UNIX, also known as PC/IX, and 386/ix were UNIX derivitives created for the IBM PC in the early 1980's. PC/IX was the first UNIX sold directly from IBM, but not the first UNIX sold for the IBM PC. (Venix/86 was the first.) The original PC/IX software sold was on 19 floppy disks and sold for 900 dollars. In 1985, 386/ix was introduced, later named Interactive UNIX. The last version released was 4.1.1 in July 1998 and was supported up until 2006.

Sun Solaris (1989) 25 Unix

Solaris is a Unix based operating system created by Sun Microsystems (now purchased by Oracle in 2010). It is the successor to SunOS and was released initially in June of 1992. The OS is based off of System V Unix and its first release was known internally as SunOS 5. This OS was typically used on SPARC based processors, up until 1994 when it began to support x86 and x86-64 based machines. Versions of Solaris up until version 8 are considered abandoned, with version 9's support ending in October 2014.
