I don't remember ever seeing an ANN for TRC, but that doesn't mean there wasn't one.  I only saw that site SixofFive linked to.  Remember there were only 16 coins around when TRC came out and it wasn't tradition yet to always post an ANN.  Also, the original dev was a very private person.  I see lots of other Bitcointalk forum threads from random people working on stuff for TRC, but no ANN.
