    assemble.zip (~22kb) Assembler v1.48 (c) 2000 by Era Scarecrow / Ryan Cecil
    It's a very simple assembler for i8086 instructions written in QBasic and producing the well-known .com executable. Exe binary is missing.

    assem120.zip (~40kb) 8088/86 Assembler v1.20 (c) 1991 by Joseph Tamburino
    This is not a complete assembler but a unit with a demo-program. It works like this: you enter the lone assembler mnemonic & then receive the equal machine code. The set of mnemonics is changeable, the file mnemonic.lst works like a script. The codification is written there in text format, readable by humans.

    d096b050.zip (~980kb) DiceRTE Protected Mode Entwicklungssystem (c) 1996-2001 Christian Diefer
    It’s a full development system for dos protected mode .pe (!!! – also works in Win32) extender based on C compiler. But also here you’ll find sources of Dasm32, a 32-bit macro assembler supporting opcodes up to Pentium III and K6-2. The syntax is Masm-like.

    dazmi116.zip (~79kb) [D]AzmIt v1.16 (C) 1997-1999 by Mikael Klasson
    It’s a very original stuff. Looking on how the main functions are used this program can both act as an assembler or as a disassembler. The two exe’s compiled in two ways are included. Dazmit accepts FPU, MMX and 3DNow! and can work with Pmode.

    Output format: .com
    Documentation: comments in English
    gasm055.zip (~45kb) Gaz’s Assembler v0.55 (c) 1999 by Gareth Owen
    This one said by its author to be NASM compatible. Accepts opcodes up to PII.

    gema26a.zip (~254kb) [G]enPC [E]lite [M]acro [A]ssembler v2.6a (c) 1994-1995 Frank Denis
    This one resembles the GenST assembler of old Atari ST. Its syntax is heavily based on Motorola 680x0 opcodes. GenPC supports mnemonics from 8086 up to P6.
    Source text: .c (GNU C, Borland C, Watcom C)
    Output format: .obj, .com , .exe (16/32 bit)

    hasm.zip (~78kb) "Home" 8086 assembler (c) 1996 by Boris Fayfel
    A “home-made” assembler with Tasm-compatible syntax. Written in Turbo Basic with a few machine code inclusions. Won’t compile with QuickBasic, so do not even try.
    Source text: .bas (Turbo Basic)
    Output format: .com
    Documentation: none, the source is commented in Russian
    inlin220.zip (~36kb) Inline Assembler v2.20 (c) 1987-1988 by Daniel Baldwin
    Turbo Pascal up to version 5.5 (if I’m not mistaken) couldn’t accept the built-in assembler constructs like asm ... end, one could insert machine opcodes with such declarations: inline($90,$90, ...). This cute proggy makes the following: it translates assembler blocks into the “inline” strings.

    intel27.zip (~34kb) Intel Assembler v0.21 (c) 2000-2001 by Era Scarecrow / Ryan Cecil

    intasm52.zip (~97kb) Intel Assembler v0.52 (c) 1998-2002 by Era Scarecrow / Ryan Cecil
    The first versions of this asm, 0.21 as well, were written in QBasic but later the author rewrote it from scratch. Now it compiles itself (!!). Pentium MMX as well as FPU opcodes are supported.

    mach10a5.zip (~29kb) One Line Assembler (c) 1997 by ???
    Something interactive. After the start-up you get the black screen a la Turbo Pascal IDE of year 1983. You enter an instruction and get the equivalent hex-code. The opcodes of i80386 processor and FPU can be used. Docs are missing. Exe binary is missing.
    Source text: .bas (QBasic 4.5)
    Documentation: no, comments in English and Dutch :)
    popasm04.zip (~132kb) PopAsm, the Popular Assembler Project (c) 2003 by Helcio Mello
    An effort to fuse all the advantages and syntaxes of Masm, Tasm, Fam and Nasm. Not compiled.

    sasm30b.zip (~231kb) Sasm, Snakessoft Assembler v3.0beta (c) 2001 by Rodney McConnell
    This one supports i486 opcodes, macro definition and some meta-directives. The outputted file is a special .sob which can be transformed to .com or .exe by slink (its sources are included). The 32-bit code for DOS-extenders is supported.
    Source text: .c (GNU C)
    Output format: .sob => Slink => .com, mz .exe

    ta980705.zip (~582kb) or ta980717.zip (~414kb) TMA macro assembler (c) 1997-1998 by Sven Michael Klose
    Not bad stuff, it resembles a86 or Tasm. IDE is also included & of course with its own sources. In addition: Dos libraries for input/output, graphics, sound blaster (wav, mod & s3m players) – many things for demomaking. The previous compiled version of assembler is included (named tmabckup.com), for making a newer build click on the install.bat
    Source text: .asm (Compiles itself!)
    Output format: .com, mz .exe
    Documentation: in English & German
