I acquired a copy of the J&R Banker for the CoCo 1 back in the mid 1990s. 
It requires background software to work in basic and IMO adds little 
utility.  Under OS-9 Level 1 it requires a patch and helps considerably with 
a RAM disk.  I have not had any luck finding out what needs modifying with 
NitrOS9 Level 1.
