You can get the SX/B 2.0 compiler files here:

You'll need to unzip the files into the compiler directory; on my system that folder is:
C:\Program Files\Parallax Inc\SX-Key v3.2.3\Compilers\SXB
Do not be concerned that it's still being called "beta" -- several of us have been using it for a long time and while we may come across a small thing from time-to-time, I wouldn't be concerned, it's very solid. And please remember that Parallax has done us all a favor -- the compiler is FREE; to get a comparable compiler with dedicated support for a PIC or similar chip would set you back $250 or so.
John and I use SX/B in all of our SX-based products (RC-4, DC-16, AP-8, FC-4... all programmed in SX/B).
Thanks so much, Jon, for taking time to put this code together. I'll be dusting off the SX board tonight and reacquainting myself with the programming and use. If things go well, you;ll be seeing a video of the end result sometime afterHalloween! If things don't go well, I'll be posting please for help!
Cheers and happy haunting!
