There is a listing of ASSIST09 in this Motorola book: 
http://geneslinuxbox.net:6309/gene/Genes-os9-stf/MC6809-MC6809E%208-Bit%20Microprocessor%20Programming%20Manual%20(Motorola%20Inc.)%201981.pdf

This might be overkill, as it has single-step, breakpoints etc.

If you type it in, note that the listing omits the second and subsequent 
hex bytes for constants (FCB) !
