Toolchains

There are any number of ways you might pick for programming the sbc and some of them are listed here.

Assemblers

The Gnu assembler gas

Pros

• it comes bundled as part of the Gnu C Compiler toolkit.
• Supports most 680x0 processsors.

Cons

• Non-Motorola syntax. Personally I hate it.

Vasm

Pros

• Supports most 680x0 processsors.
• Uses Motorola standard syntax
• Powerful macro support
• Can produce output in multiple formats:
  • S-Records - great for building standalone images ready to upload directly to the sbc.
  • elf - code assembled to elf can be linked with other elf files (which could be assembled code or compiled C).
• Can be compiled on just about any platform with a half decent C compiler.

Cons

• Can't think of any.

Compilers

gcc-m68k

For me, it's a no brainer to use this wherever it's available. I do most of my development under Linux and gcc-m68k is available to install on all but the most obscure Linux distros.
