If the Rowe five dollar upgrade board was released and for sale, this is how you would change it out (like a how-to for a product that does not exist). You first take out the CCC board from the Rowe changer. (I lost this guys business card so unfortunately I can not give out his information. I need to try and get this information from my dad.) The first picture shows (red arrow) the board that will be replaced. The second picture shows the board that you will get in the mail. The distributor said that the kit will also come with 2 chips like the one next to his thumb. He also said that the chip on your old board will be labeled and that type needs to be on your new board. He is also pointing at the notch (third picture) that you have to line up with the notch on the ccc board. Looks pretty easy and he said he will be selling them for around $66.
Update: I believe that I found his business card. Jess Vasquez from Baca’s Changer Service & Sales Inc. bcschangers.com
