vasm is a portable and retargetable assembler to create linkable objects in various formats or absolute code. Multiple CPU-, syntax and output-modules can be selected.
Many common directives/pseudo-opcodes are supported (depending on the syntax module) as well as CPU-specific extensions.
The assembler supports optimizations (e.g. choosing the shortest possible branch instruction or addressing mode) and relaxations (e.g. converting a branch to an absolute jump when necessary).
Most syntax modules support macros, include directives, repetitions, conditional assembly and local symbols.

Dead Hackers Society Atari ST/Falcon files section. There you will find all popular and more obscure native Atari productivity tools for graphics, music, programming and demo creation. Each entry is well described, so everyone who is new to the platform will have good overview how everything looks, what features it has and will be able to choose something for themselves. Highly recommended .

This website is dedicated to two tools written specifically for the Atari range of machines.

rmac is a macro assembler targetting the 680x0, 6502, Jaguar JRISCs (codenamed Tom and Jerry), Jaguar Object Processor, and the DSP 56001 CPUs. It can output to standard aout object file format, ELF, or directly to Atari TOS PRG format or absolute binary.

rln is an object linker that can output raw binaries at an absolute address or COFF binaries (a common format for Atari Jaguar development).

Collection of the old code base for the TurboAss and Bugaboo, which was first sold commercially under the name OMIKRON.Assembler and later as shareware under the name TurboAss/Bugaboo.

Features:

68000 assembler, editor and debugger
Compiles up to 1.3 million lines per minute (on a 8MHz 68000)
Syntax check at input!
very powerful editor
source level debugging
does not depend on the operating system

Adebug/Assemble is a pair of Debugger/Assembler for the MC68Xxx family running on Atari and Amiga computers. Years ago commercial product, now GPL.

ultraDev is a FGPA based development cartridge for Atari computers.
With ultraDev you are able to start .Prg files directly from your PC on your Atari via pc command line. ultraDev is also able to share a folder from your PC to your Atari as a volume.

A collection of brown scripts that build brown compilers and libaries for the Atari ST series of computers. Allows to build latest gcc compilers for m68k targets. It's using elf output, which has to be preprocessed to Atari binary format.
