asm68c
Assembles M6800 and 6801 assembly language source code. (and Forth)
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.)
