San Bergmans has released SB-Assembler 3

Download here.

Now written in Python 3, runs on Windows, Linux, Max OS.

New Features Of The SB-Assembler 3

• Will now run on Linux, MAC and Windows machines.
• Written in Python3, a modern multi-platform programming language.
• Source files will be included, allowing you to create your own cross overlays.
• Local labels from other global labels can now be accessed.
• Can now generate warning messages where errors would be inappropriate.
• Include source files can now be nested as deep as you like.
• Separate target spaces for code memory, RAM memory and EEPROM memory.
• The .TA directive can be used to map generated code to the ROM address map easily.
• More room, we can now use Giga bytes, in stead of some 550k bytes to do the job.
• As from Version 3.01 label and macro names may also start with an underscore.

Familiar Features Of The SB-Assemblers

• Can cope with an unlimited number of source files, each of unlimited length per assembly run.
• Can create an unlimited number of target files, each up to 4 GB in length per assembly run.
• Supports many output file formats, like Intel Hex, Motorola, Hex, Bin, etc.
• Simple command line structure (No obscure switches and options to remember and type each time).
• Produces directly rommable code, no linking required.
• Mixed processor support (2 or more different Crosses can be used per assembly run).
• Easy to distinguish directives from mnemonics (Each directive begins with a dot).
• Global and Local label structure, eliminates labels like LOOPXX and LOOPXXX.
• Automatic comment field. No ; or * required to start the comment field at the end of the program line.
• Conditional assembly capabilities.
• Macro support.
• Crosses available for most popular 8 bit processors, like 6502, 8080, 8085, AVR, Z80, and many more.
• All versions are almost 100% compatible with each other.
• And best of all: It’s completely free!
