Michael, I bought a RockPro64 4gb and I have rt_preempt running on it. However, they keep moving the goal posts. I have been unable to get rt_preempt to run on a newer release. If I lose the uSD I have (or if I find a bug in it) I can't produce a newer image. The people most involved in it seem more interested in video streaming or something like that. All of the images (and source for them) that they are releasing are heavily patched so you can't apply rt_preempt patches to them.
At the moment, I wish I had waited and bought a Raspberry Pi 4b (4gb). It has the same processor, and a whole lot more people working on software. It has a relatively current rt_preempt kernel available for it, without even having to configure and compile it. The Raspberry Pi 4b, is not quite as fast but it has gigabit ethernet, USB3 and wifi built in. It doesn't have quite as good heat sinking available at the moment. The Pi 4b doesn't have a pcie slot but there is some question about driver support for the pcie slot on the RockPro64.
