MOTM

Being a relative newbie at MOTM , I read of some modules that I can't seem to find in the 
catalog (a 110 is mentioned at a Robert Rich demo of the 101 for example)

Is there a list of MOTM module numbers that were produced in the past, what were they, and 
what have they been succeeded by (and why perhaps? :-)  )

Thanks, Merry Christmas and a great New Year to all of you.
