A simple absolute mode assembler for 6800/6801. Handles the complete published set of opcodes/mnemonics. Mostly source-language compatible with the common assemblers in use circa 1985, but no macros.

Now uses standard LDAA syntax by default.

Produces basic S1/S9 object files and assembly listings, and now binary and MC-10 compatible cassette images.

(This is for the 8-bit 6800, not the 16/32 bit 68000/coldfire processors.)

Features

  • S1/S9 output
  • Optional binary or MC-10 compatible .c10 output
  • Switches between LD A and LDA A syntax
  • Includes the fig-forth model for 6800, as a test file.

Project Samples
