I thought this was interesting…. This is a Hamilton ACW controller with v4.23 firmware installed on the chip. With a 49-1200a REV 3 board from 1996. I am assuming this is what Hamilton charges $150 for (The jumpers)? I assume this is ready to upgrade to the “c” version firmware also? You would have to ask super Randy.
I have the stainless case also. If you want to purchase it let me know. I also have the whole ACW part. 🙂
All I want to know is… If this controller is undated to v4.23 wouldn’t my ACW now be a ACW 5? What was the difference? Besides that switch on the relay box?
