Actually, it looks like the LRtech Superboard was a SCSI adapter for the 
CoCo (3) from a little later on in the '80s, so it might have been code 
for the rma assembler instead.  I'm not sure I could tell the difference 
at a glance.  May have been developed on a CoCo 3 in OS-9 Level II.  But 
it is definitely OS-9 device driver and device descriptor code.
