ASM86 is a tool that compiles 8088/8086 assembler mnemonics in to machine code. The resulting machine code modules must then be processed by the separate Intel iAPX 86-88 Family Utilities.

DB86 is a debugging tool from Intel for use with Intel language products.

A set of utilities for use with the Intel Intel iC-86 Compiler and Intel PLM Compiler.

iC-86 is an optimizing C language compiler from Intel for the 8088, 8086, 186, 286, and 386 processors.

PLM is a high-level programming language with many low-level features, originally developed in 1972 by Gary Kildall. PL/M was the first high-level language for microprocessor-based computers, and was used to implement CP/M. The Intel PLM Compiler is a tool that compiles PL/M to 8088/8086 machine code.

Lattice C was originally released by Lifeboat Associates in June 1982 for the IBM PC. Microsoft repacked Lattice C as "Microsoft C 2.0", however Microsoft C 3.0 and later used Microsoft's internally developed product instead. Lattice C was ported to MVS, VMS, Unix, OS/2, Amiga, Atari ST, and Sinclair.

Borland Lightning Word Wizard is a set of development source code and sample programs that enable you to make use of Turbo Lightning advanced database engine features from within your own programs.

Back before Logitech just sold mice, they produced a programming development system based on the Modula-2 language. efficient native code, and included a symbolic debugger. There were versions for both PC-DOS and CP/M-86.

The Logitech Pascal to Modula-2 Translator is a programming tool that converts Pascal source code in to code that Modula-2 can compile and run. This was an attempt to reel in users of the very popular Turbo Pascal programming product.

The Mark Williams Let's C compiler was powerful C compiler for MS-DOS. Let's C was a subset of the Mark Williams C Programming System, and the first low cost entry-level professional C compiler for the IBM PC. It was also the first compiler to have a C source-level debugger. executables than any other compiler on the market at the time. It supports both large and small x86 models, and supports the 8087 math co-processor. It competed against compilers from Digital Research, Lattice, Computer Innovations, and Microsoft. language, plus extensions to C implemented under UNIX. Includes an assembler, loader, archiver, advanced symbolic debugger. C shell, utilities and Micro-EMACS, a full-screen editor. Unix and the Atari ST. Let's C is fully compatible, so C programs can easily be ported between the ST and IBM PC. Coherent, the first commercially viable Unix clone.

MetaWare High C/C++ is a very robust cross platform compiler for DOS, Unix, OS/2, Windows, and Windows 32. Originally a C compiler targeting CP/M and DOS, 'Metaware High C/C++ was later extended to support OS/2 and the 80386 architecture. After the failure of Metaware it was taken over by MQX Embedded who re-targeted it at the embedded market. MQX Embedded is now Synopsys and the product is now referred as Synopsys Metaware Compiler with no OS/2 version.

Micro Focus COBOL is a powerful high-speed COBOL language compiler that supported cross platform development between DOS, Windows, OS/2 and Unix. It features an interface developer for both GUIs and text mode, a code debugger, a code analyzer, and later versions included support for object oriented code development. It claimed it made COBOL programmers more efficient, while speeding up migration from mainframes to personal computers.

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's Business Basic Compiler is a special BASIC variant that is designed to create high performance compiled code, with a focus on numeric floating-point accuracy and additional database-like features.

This is the original standalone Microsoft C/C++ compiler for DOS and Windows - Later versions were rebranded and renumbered as Microsoft Visual C++ and were bundled with Visual Studio or the SDKs.

Cobol is a high level language designed for use in business that uses English-like commands. Microsoft got its early start by producing language products such as this one. Their other early language products included Microsoft Fortran, Microsoft Pascal, Microsoft Basic, and Macro Assembler. This product was also licensed to IBM as IBM Cobol Compiler.

This is Microsoft's implementation of the FORTRAN scientific-oriented high level programming language. It was one of their early core languages developed for the 8-bit computers and later brought to the 8086 and IBM PC. For the IBM OEM version, see the IBM Fortran Compiler. In 1993 Microsoft rebranded the product as Microsoft Fortran Powerstation. (Note: -80 refers to the 8080/Z80 platform, not the language specification version)

Microsoft Game Shop is a development tool for creating games in QuickBASIC. Microsoft Game Shop includes a full-featured version of Microsoft's QuickBASIC 4.5 interpreter plus six classic computer games, including a version of Tetris that you can both play and modify using QuickBASIC.

Microsoft LISP, originally developed by Soft Warehouse, of Honolulu,is a high-speed LISP interpreter sold alongside Microsoft’s other language products. LISP is a programming language based around symbolic expressions. It was used to develop expert systems and "artificial intelligence" systems. Microsoft LISP features a large number of native functions and includes a debugger.
