| Eric Isaacson's ShareWare Assembler and Debugger | ||
| File Name: | A86/D86 (A386/D386) | |
| Location: | http://www.eji.com/a86/ | |
| Version: | 4.05 |
This assembler doesn't require any "red tape"/directives to assemble a file directly to a .com file. However, for ease of use and outputs other than .COM, directives are required. A86 will create output files in the following formats: .COM, .OBJ, and .BIN (image files). To get the higher processor capabilities, you must purchase the A386/D386 package. However, recently, the author has included some instruction on how to create Windows programs. |

|
| Version: | 1.67.38 |
I have not used this assembler yet, but after reading some of the documentation, it looks to be quite a nice assembler and growing quickly. It will output several different types of file formats: .COM, .EXE (MZ and PE), .COFF, and output for .DLL type files. (LINK not required) The DOS assembler included requires a TRUE DOS environment. |

| Version: | 0.56.6b |
Compared to many other offers, it is interresting because Jeremy also
wrote and provides a Linker, a Debugger, and several other things of
interrest, that make the whole offer really 'consistant'. This is a Win32 only Assembler released under 2 versions, freeware and shareware. |

| File Name: | ASM | |

| Version: | 1.12 | Nice little 80x86 assembler. The part that caught my eye, was that it would write your code right to the boot sector of a floppy if you asked it to. Hence, I had to add this feature to NBASM :) (Thanks Bert) |

| Microsoft Macro Assembler | ||
| File Name: | MASM | |
| Location: | http://www.microsoft.com/visualstudio/eng/products/visual-studio-express-products | |
| Version: | 8.xx |
This assembler is somewhat supported by Microsoft and will still create DOS programs if you use a DOS segmented linker. If you adhere to the License Agreement, it is free for download. Output formats: .OBJ (MZ & PE), .COM, .DLL, Windows etc.) This version only runs in a Windows Console. If you can get version 6.11d, it will still run under TRUE DOS. There is version 8.xx out now, so I have heard. The way to get it, legally, is to register and download the Visual Tools package, install, then look under the bin directory. Since Microsoft changes their links so often, the link above may not be valid for very long, or it may point to the wrong place. Find the Visual C++ download package. |

| Run OS: | Windows Console* | |
| Target: | Windows Console*, DOS | |
| Type: | Commercial ("Free") | |
| Open Source: | No | |

| Cons: From Microsoft. | ||
| Netwide Assembler | ||
| File Name: | NASM | |
| Location: | http://sourceforge.net/projects/nasm | |
| Version: | 2.06rc10 |
NASM is noted for its vast output formats and portability. It is written in C and source code is included. It outputs a.out (linux), ELF, NetBSD/FreeBSD, .COFF, MS .OBJ (16-bit and 32-bit). NASM uses a somewhat different syntax for memory (label/etc.) accessing than most other assemblers. Not to say it is wrong, just a different syntax than MASM, TASM, NBASM, etc. Once you learn how to use it, NASM is a nice assembler. Get the IDE at: http://uk.geocities.com/rob_anderton/ |

| NewBasic Assembler | ||
| File Name: | NBASM | |
| Location: | https://www.fysnet.net/newbasic.htm | |
| Version: | 00.26.56 |
NBASM was designed to be easy to use and doesn't need a lot of command line arguments. NBASM outputs DOS 16-bit and 32-bit code for .COM and .SYS file formats as well as the 16-bit .OBJ format, including a linker (NBL) ready for these .OBJ files. The advantage of NBASM, it is always being updated and worked on by requests from its users, including its main user, me :). The disadvantage, it is always being updated and worked on :) It doesn't support all of the most recent instructions, though this version now contains a lot more of them as well as some that I missed before. However, NBASM is very easy to learn and is fully supported by the author. It also includes a disassembler. Get the IDE at: https://www.fysnet.net/nbasmide/nbasmide_help.htm |

| The Specific Assembler | ||
| Name: | SpAsm | |
| Location: | http://betov.free.fr/SpAsm.html (Broken) | |
| Version: | 4.15d / 2.050a | I have not used this assembler, but the author states (thanks rené) that it doesn't require any red tape, has a vast macro capability, and includes an all in one IDE. No seperate tools required to create executable programs. No installation, just copy and use. Great debugging of .EXE files, since SpAsm places the source right in you .EXE (optional). Fast assembly and integeration of Windows equates, structures, etc. I really think it is worth a look. Really... |
