How can we get the old 1.83 from using GitHub download?
Regarding this question, you can look at a post I wrote a while back:

Also, I haven’t updated the pre-configured SD card image yet, so the current image still has 1.8.3 installed. I will make a new image soon with 2.0 but will keep the 1.8.3 version just in case someone wants to go back to it.
