In his article on page 47 of the Nov/Dec 2006 N Scale Magazine, Ron Beardon defines six groups of DCC readiness based on like amounts of work required to install the decoder.

Below is the first attempt. Conversion information on the internet is noted where available. These are also an excellent source of disassembly instructions.
